Kim Kai makes little to no sense to Oh Sehun. The older has a couple tattoos, some piercings, dyed grey hair, and a mean face when he wants to have one--- But, Kim Kai is also one of the nicest guys on campus. He's got a bright smile and a loud, hearty laugh. He is humble and kind, and pretty smart too. However, was it mentioned, that Kai has a son? No? Yeah, Sehun didn't know either. Until, that is, he gets invited to the older's apartment after school.
