A hero saving a beauty is the beginning of a love story. So, what is a beauty saving a hero?
Xi Ai rescued Xu Yimu from a group of gangsters as a girl, so he shamelessly became Xi Ai's innocent, cowardly and introverted little follower on the pretext of repaying the favor of saving his life.
He thought he could keep pretending for her, but when Xi Ai went to Japan, he thought he could keep her by crying and confessing. However, there was always a but, Xi Ai told him that she hated his cowardly character, no, it was disgusting.
He thought that restoring his original personality would bring her back, but Xi Ai never came back.
... Everything, just what he thought...
He said, Xi Ai, I can wait...
She said, Xu Yimu, just wait and eat shit!
