Two people met in Chinatown.
A boy who has vague memories of the past and even lacks common sense.
The young owner of the restaurant took in the boy like a stray cat.
The mysterious boy slowly emerges his true memories.
Even if you try hard to forget, once you think of it, you can't break the bond again.
The returned memory is the thunder that forces the end of a peaceful life.
I will return to you soon, whose oath is it?
