Tang Wangyou lost his memory. He didn't know who he was or what he had experienced. I don't even remember why I turned into a ghost. He didn't even remember what he was going to do, so he had no choice but to wander around the world as a lonely ghost. Until he met a heartless and funny guy.
This is a difficult mystery. None of them can leave the other person, and no one can accept the other person. Obviously we are meeting again in a foreign country, but we don't recognize our old friends.
The fate between them is both extremely unlucky and extremely lucky.
