In the nine reincarnations, every year is a calamity, and every step is a disaster. He and she traveled through the world's fireworks, mountains and seas, temples and rivers and lakes. They met at the right time in every life, but they fell in love so much that they couldn't help themselves. There are childhood sweethearts who are hard to reconcile, there are lovesickness that is separated by mountains and rivers, there are people who cannot help themselves due to the intrigues of the court, and there are natural chasms that are difficult to cross between immortals and mortals. The tokens are warm and cold, the obsession is deep in the bones, from black hair to white hair, from the first meeting to the farewell, every embrace has a prophecy of separation, and every stay together cannot withstand the overturn of fate. Nine lifetimes of deep love, nine lifetimes of sadness, going round and round, just asking for one thing year after year, but in the end only result in passing by each other and missing each other. Is this obsession that transcends reincarnation a deep-seated lovesickness, or an inextricable shackles of fate?
