D.O. is suspicious.  Something is definitely up.  Not only with his band mate, Chanyeol, but also with his cousin, Naeun.  He's always been protective of Naeun,  being the only family she has in Seoul.  When he stumbles into an amorous scene between the two at EXO's dorm, he doesn't know how to respond.  How can he approve of this relationship when he knows it could put both their careers in jeopardy?
