With theo.. okay so theo is like gross boy but he's also a little bitchy gay as well as truly being "just some guy" and it's like!! He truly to me seems like he'd be down for anything and playing along. So taking all this into account.. it can't be myungjae he needs to be told what to do. Sungho is too polite pushover and even riwoo is too, tho riwoo has more bite to him. So im thinking taesan, purely because hes more outgoing than leehan is (they occupy similar realms in my brain, namely being perverts, leehan is just more reserved). I also just love putting theo with younger guys and making him Deal With It, having to figure out how to handle them.. taesan asks for his underwear after he jerks off and theo laughs at him but says yes anyways in fond exasperation type of thing
