In the empire of Tang, a Taoist sect called Xuan-Xin Zhen-Zong discovered an ancient stone tablet in a mountain cave. The tablet contained prophecies about the Estranged Couple of Seven Lifetimes, with the demon sect Moon Kingdom seeking to exploit their power. Jin Guang, the Grand Priest of Tang, and his elders Yan Chi Xia and Sima San-Niang protected the newborn babies of the couple, but Moon Kingdom managed to seize the baby girl. Yan Chi Xia and Sima San-Niang fought back, allowing the mother to escape with the baby boy.

Eighteen years later, scholar Ning Cai Cheng sold imitation paintings to support his mother's medical treatment. At Ruolan Temple, he encountered Nie Xiao-Qian, the baby girl who had been taken by Moon Kingdom. Nie Xiao-Qian, transformed into a fox spirit, sought true love among mortals. She encountered Mei Ji, a spider demon, who used her for demonic purposes. Nie Xiao-Qian attempted to make Ning Cai Cheng fall in love with her, but he discovered her true identity and fled.

Zhuge Liu-Yun, a disciple of Yan Chi Xia, rescued Ning Cai Cheng and learned of Nie Xiao-Qian's quest for genuine love. Sima Hong-Ye, daughter of Yan Chi Xia and Sima San-Niang, encountered Nie Xiao-Qian and initially wanted to destroy her. However, they discovered they belonged to the same sect. Zhuge Liu-Yun and Sima Hong-Ye had conflicting feelings for each other but held the key to resisting the demon realm.

A battle ensued, resulting in Yan Chi Xia's injury and the death of Qi Ye. Xiao Qian died in Ning Cai Cheng's arms. Twenty years later, Liu Yun encountered Ning Cai Cheng at a market. There he saw two girls who resembled Xiao Qian and Hong Ye. Upon closer examination he discovered it was not them. Nonetheless, when the two girls found a painting of Xiao Qian and Hong Ye it brought great joy to Ning Cai Cheng and Liu Yun.

• Nie Xiao Qian (Barbie Shu)

She is one of the ‘star crossed lovers’. She is a talkative and kind fox spirit but she can also be very willful to take things for granted. When she does not get her way, she throws tantrums. See how ungrateful and selfish she can be to say words that hurt Hong Ye and Qi Ye despite of how both have helped her!

She is helpful to try to make Yan reconcile with his wife. Xiao Qian can be so unwilling to believe that Qi Ye is the star crossed lover. She still insists that Cai Chen is the one although the evidence is shown. Poor Qi Ye is at his wits’ ends to try to explain his intention to find out whether they are the star crossed lovers. Yan does the talking for him and she realizes her mistake.

• Ning Cai Chen (Daniel Chan)

He is one of the suspected ‘star crossed lovers’. He falls for Xiao Qian and tries to rescue her from marrying the Black demon. He gets poisoned and dies before they are married. He is completely cured by Yan and he shot an arrow at Qi Ye.

• Qi Ye (Nie Yuan)

He is Yin Yue empire’s young lord. His surprising real identity - he is Cai Chen’s twin brother! Even before he knows his identity, he wants no suffering to mankind and tries to build up a humane demon world.

He looks very distant and cold but he has a warm heart. He loves Xiao Qian and gives in to her all the time. Knowing that she is in trouble, he comes personally to rescue her from the black demon. He keeps his promise to her in taking care of Xiao Xue by bringing her to the Dark Palace. Qi Ye is upset to know that Gan Jiang is his previous lifetime. He is the ‘star crossed lover’ and not Cai Chen. His attitude to Empress Yin Yue never changes – still treating her like his mother. He moved to the mortal world and becomes a fortune teller to have a simple life with Empress Yin Yue. However, he still wishes to confirm whether he is the star-crossed lover. When he really is, he decides not to see Xiao Qian again to avoid tragedies.

Mrs Ning dies in an attack on their wedding day. He gets so upset that he becomes a demon again and has a sad ending to die in Cai Chen’s hands.

• Zhu Ge Liu Yun (Wu Jing)

He is Yan’s disciple who loves Hong Ye. He is talkative, playful and boastful. In an attempt to save Cai Chen, he says that he can do it but fails miserably – the talisman falls in front of him despite his repeated attempts to raise it!

Many will shake their heads on the way he reveals Cai Chen's 'star crossed lover' identity out of rage. It puts his life into danger and Hong Ye has to protect him. Yan tells him to look for Wu Wei. Wu Wei tells him that he is the son of Qing Tian and Lanmo. He protects Lanmo and dies when the moon demon tries to kill her. The two brothers are on good terms after the ordeal. He becomes sensible and mature. He is no longer reckless and can help San Niang analyze problems when she discusses with Yan over the important issues. The couple is baffled but glad that he changes so much. Liu Yun is upset to know that Wu Wei died to protect Hong Ye but does not hesitate to admit that he will do the same too if she is in danger. The white-haired Hong Ye wishes to kill him because he is a half-demon. He finds it ridiculous to fall for her and is so upset when she dies to make the normal Hong Ye return. He has loved her after kissing her and both write tablets with each other's’ names at the lovers’ temple. He takes a long time to accept the real Hong Ye again.

• Zhu Ge Wu Wei (Bryan Wong)

He is Liu Yun’s wise elder half-brother. He refuses to be one of the perfect lovers to have a quiet life with Lanmo. He knows no martial arts but learns the shield from Tian Xin to protect Lanmo. He regrets his choice of rejecting Yan upon seeing how pretty Hong Ye is. He has thought that his daughter will be as ugly as him! In order to rescue Hong Ye from Tearless city, he locks himself with Gan Jiang in a cell and is killed. Even before his death, he still tells Hong Ye to try to love his younger brother.

• Si Ma Hong Ye / Hung Yip (Jessica Hsuan)

She is Yan’s daughter and inherits San Niang’s fiery temper. She loves Cai Chen but is irritated by Liu Yun’s presence. She presses Xiao Qian and Cai Chen to marry so that she will end her own wishful thoughts. It is funny that all can see through it except the blur Cai Chen! It is also strange that Cai Chen does not recognize her when she suffers one attack and tries to kill him before the wedding. How can he not know her because her face does not change and only her hair turns completely white?

The vital energy makes her lose control finally and becomes unfeeling. She can’'t even cry when Wu Wei dies for her. So she asked a favour to Xiao Qian to shed tears for him. How does she become the white haired Hong Ye? She prefers to deceive herself and remain in her dream. Liu Yun enters her dreams in order to get her out. However, Liu Yun manages to make the white-haired Hong Ye understand mortal feelings and love. Both fall in love and he finds himself not liking the normal Hong Ye that much although she recovers. Both manage to iron out their differences to fall for each other again. But their romance is short lived when she dies after injuring Qi Ye seriously.

• Si Ma San Niang (Tien Niu)

Chi Xia’'s hot tempered wife who does not like him to think only of others before himself. She is a skilled physician. She is displeased when Yan teaches Hong Ye ‘Xuan Xin mystic’ because she is the ‘perfect lover’. Once she starts practicing, she can'’t stop and will die after killing the demons at highest level. The couple quarrel and separate for 10 over years. She thinks that he stays near the spring to get Mo Xie sword to atone for his sins – so that Hong Ye will not die when using the sword. After knowing that Yan decides to kill himself to subdue the sword in the Dark Spring to prevent the evil forces from coming out, they finally reconcile. Strange but she finds more affinity with Qi Ye than the others so she unofficially acknowledges him as her godson. A pity that she dies in his hands but she disallows Yan to seek revenge.

• Yan Chi Xia (Yuen Wah)

San Niang's husband; Hong Ye's father. He is the demon catcher who sacrifices himself in helping others. He risks Hong Ye's life to master Xuan Xin mystic to save mankind. He nearly loses his senses when he tries to stop the Mo Xie sword coming out from the Dark Spring in Wan Qing forest. His family forgives him for his mistakes and they are reconciled.

• Xia Xiao Xue (Kimi Hsia)

She is Xiao Qian’s close friend, a snow spirit also captured by Mei Ji. She is gentle and quiet. She is alert to detect the Empress Yin Yue has changed and Qi Ye's affections for Xiao Qian. She falls for Qi Ye and understands him well. She happily prepares for Xiao Qian's wedding, only to be there to help to save Mrs Ning unexpectedly she stands beside Qi Ye to treat Mrs Ning while Yan and San Niang sit on the bed to treat Mrs Ning. They look so compatible when he places needles on Mrs Ning while she checks her pulse - Qi Ye can be so blind only to fall for the unreasonable and unappreciative Xiao Qian!

To protect Qi Ye, she does no’t wish him to know his actual identity. She even shields him in Tearless City and is killed. It is so sad when she fulfills her promise to give him her life when trying to uncover his secret at the illusion pool earlier. She is contented that Qi Ye hugs her before her death

• Jing Wu Yuan (Bernard Tan)

He is Lanmo'’s elder brother. He looks evil but he isn't. He is also Qi Ye’'s martial arts teacher and advisor. He killed the moon demon many years ago and has high status in the Yin Yue empire. He does no’t know that Qing Tian is from Xuan Xin sect and even introduces him into the Yin Yue empire. He later lets him elope with Lanmo. When Yin Yue empire is in trouble because of Qi Ye’s identity, he still stays and many even choose him to be he next lord.

• Jin Guang (Shen Xiao Hai)

He is the ruler of Xuan Xin sect. He wanted to kill the infant star crossed lovers but was stopped by Yan and San Niang. Both can'’t bring their hearts to kill the infants. He is ruthless to kill their parents instead. Also jealous of Hong Ye to be the master of Xuan Xin mystic so he also masters it immediately after discovering the scroll. This is against the rule. He masters it so soon and is more powerful than Hong Ye. But the founder deliberately writes it the wrong way so he has a worse fate than her. She turns unfeeling but he loses all his skills! Before he is cured, he is the underdog and even kneels in front of Hong Ye to beg her. But after he recovers, he becomes arrogant again.

He is despicable to feign to agree to Qi Ye and Xiao Qian’s marriage to end the dispute between morals and demons. But he breaks the promise and kills all demons, including Mrs Ning. This causes the kind and filial Qi Ye to be badly affected and become evil.

• Empress Yin Yue / Tree Demon (Zhu Yan)

She is Six demon'’s wife and is a tree demon. She is seriously injured after San Niang hits her from the back when she flees. She has a miscarriage so that is why she hates Yan and Lanmo so much. She prays to the moon god but the moon demon comes instead. She lets the moon demon possess her (she enters others’ thoughts and is a big danger to Yin Yue sect) to make Lanmo suffer. She sets a curse on Lanmo and Lanmo sets a curse on her in return. I really laugh when Lanmo says the curse is actually a form of gift! Lanmo declares that she will never recover unless she finds true love again. Lanmo finds Qi Ye a better son who can make up for the son which she has lost. Actually, she sheds a tear when reading her story but the moon demon reminds her so hatred is built in her heart again.

She really dotes on Qi Ye. However, her greed for power overcomes her. She pretends to give Qi Ye and Xiao Qian their mortal bodies back but she is still interested in making all mortals to become demons. Qi Ye kills her and Liu Yun is saddened that she has tried hard to help when she regains her senses but things still turn out this way.

• Mei Ji / Spider Demon (Teresa Mak)

An evil spider spirit which controls Xiao Qian in the beginning. She tricks Xiao Qian to find men to increase her powers. She is Empress Yin Yue’s close friend and comes to stay in the Dark Palace. She sheds tears after reading Lanmo’s story. The 4 guardians are after her when they think that she is responsible for Empress Yin Yue’s ordeal. She brings Lanmo’s book with her and is curious about love. Can you believe that she lets men off now even though she feels hungry? Upon seeing that she has changed, Yan allows her to take care of Yuan Hang. She is genuinely in love with him but she gets poisoned. Yu Er does this to her when Mei Ji can't bear to kill her. The poison makes her reveal her real form and Yu Er lies that ‘this spider demon’ has killed Mei Ji. She requests Yu Er to keep the truth from Yuan Hang before she dies. Despite this, she is contented to find true love in the mortal world like Lanmo.

• Su Tian Xin (Sheren Tang)

She is Mo Xie'’s cousin and Gan Jiang’'s ex-love interest. She has magical powers and witnesses her 3 friends’deaths on the same day.

She can only reduce his grief through the writing of love stories and trying to find more to write on. Since then, she hasn't grown old all the 7 lifetimes!

She is curious to know about Qing Tian and Lanmo’s love. She cooks up the story about the 100 candles as she knows that there is no cure for Liu Yun. Liu Yun is destined to die even as an adult. However, she is touched when Lanmo manages to create miracles repeatedly. She brings Wu Wei to the Tearless city to make him and also others to know about the past. She has hoped that Xuan Xin mystic can help to reduce the demonic power. But Hong Ye disappoints her because she is untrue to her feelings. The surprising part is she writes the skill but she does no’t master it! Qi Ye, Wu Wei, Hong Ye and Xiao Qian are lured into the city. Upon seeing Gan Jiang suffering for long, she jumps into the furnace to be the heart of Mo Xie sword. It finally kills him and leads the rest out of the city.

• Mrs. Ning (Pan Jie)

She has all along wanted a peaceful life after the ordeal and suffers from amnesia. She is very forgetful but sometimes can remember important details. She remembers Xiao Qian well - maybe because of too many repeated scenes that make her reveal her true fox demon form? She is overjoyed that Qi Ye is her son. But their reunion is short-lived when they meet again for the second time on his wedding day.

• Shangguan Yuan Hang (Hang –Cheuk Fan)

He is Jin Guang'’s nephew and is a kind general who is dying of sickness. After Yu Er saves Mei Ji, he falls for her and she looks after him. They fall in love and he proposes to her.

She calls herself the new lord. but Qi Ye, the previous lord, has more talking power to persuade the demons to change their minds. She is made use by moon demon and poisons Mei Ji, thinking that this will prolong Yuan Fan’s life. Still, she is depressed when Mei Ji chooses to die by her sword. She later regrets her decision when Yuan Hang becomes unfeeling so she kills herself.

• Madam Ping (Yuen King-dan)

Ping An's mother, very exaggerated in the way she is in ‘A kindred spirit’.

• Ping An (Apple Hong)

She is a village girl who is not afraid to tell her feelings to Liu Yun. But, she is too desperate to offer herself to him when she thinks that he has killed the fire dragon. I detest her to frame Lanmo for the forest fires that she herself causes. Poor Lanmo takes the blame for so many times! This selfish woman wants Liu Yun to stay with her forever! But her efforts come to naught when he still wants to leave.

• Zhu Ge Qing Tian (Jackie Lui)

He is Yan’s junior who falls for Lanmo when he goes undercover in Yin Yue sect. Both sects can'’t condone his act when Lanmo is pregnant with his child. He still returns for her with an injured arm.

But under Empress Yin Yue’s curse, she is turned into a fire dragon immediately and can’'t revert to the human form again. Both are forced to part for 20 years. She helps him to be a hero by pretending to be killed by him. She also helps him to burn a route for the villagers too. When Liu Yun dies a second time, she does the same begging but it does no’t work this time. So she gives up her life for him but is reassured that her son has grown up.

He is a despicable man who poisons his senior, Gan Jiang in order to get his junior, Mo Xie. Gan Jiang burns himself to death after he turns mad. Yi Xi knows that they are in love. He has four unsuccessful tries to break his master’s sword into two. Seeing how Mo Xie is so determined to die instead of being with him, he becomes revengeful and curses them for 7 lifetimes before becoming Yi Xi sword. His next lifetime is the Yin Yue empire’s first demon lord – that is why Yi Xi sword symbolizes the imperial authority like an emperor of the empire too. Another surprise at the end – he is Cai Chen’'s pastlife!
