Jin Xiu, the King of the Central Heavens, intended to help a little camellia demon become immortal but he became mortal for her in the end. At the Flower Festival held once every 100 years in the heavenly realm, camellia demon Hong Ning boldly confessed to Jin Xiu her intention to become his queen. When she is told that demon and god can never be, she takes his advice to heart to cultivate and achieve immortality. Upon her ascension, Hong Ning learns that Jin Xiu is marrying someone else. She resolutely abandons an immortal life to enter the cycle of reincarnation, simply to forget him. Jin Xiu defies fate itself in order for Hong Ning to be reborn. He hopes to repay his debts and protect her for a lifetime. A misunderstanding that cannot be avoided, an identity for which there is no escape; when spring ends, the two meet again. Hong Ning is destined to become Jin Xiu's trial in love. Adapted from the novel When Spring Ends, I'll See You Again (落花时节又逢君) by Shu Ke.
