Love and hate meet, parting hurts, and you can't ask for anything.
He is a demon, and he is a Taoist priest. They should be strangers. A chance encounter destined to be a lifelong entanglement.
The first time he turned from a demon into a human, he said, "I don't believe you."
The second time he was transformed from a human being into a spirit. He said, "The world is too bitter."
After he was reincarnated, he gave him a name. But they forgot each other.
Can two people who have become strangers still fulfill their vow to hold hands and grow old together?
