One day, she introduces herself to him without letting him know about her illness. He is Kji Fujishiro (Takashi Tsukamoto) When her cousin drags her home, they sit by her window while they watch Kji meet his friends.

Fai must go on the run, but he no longer trusts Feng, who he believes may be leveraging their brotherhood for advancement in the police ranks.
