There already is topic on this, but who cares. How do you think Ken's identity as a boss will be revealed to Sun and Yumin
I'll be straight, I have no idea xD, Maybe Yumin (even though she horribly hates gangs, mafias, etc) will join Ken's gang to take down her father, but I don't know because of what I said before. SHE HATES GANGS WITH HER WHOLE HEART xd
EDIT: Btw your image is from that manga (I don't remember the name) that the protagonist is a vampire called Staz, right? :D
