It'll turn into Operation stud-hunt with the female MC, Yukari and a reluctant Mitsuru.
...can you imagine....
I think it would be hysterical if they caught the guys babe-hunting, striking out badly, then doing the whole point and laugh. Face it, what girl doesn't find it funny to see guys make asses of themselves around other girls? Heck, us guys find it funny too.
EDIT: And why wouldn't the female main participate with Mitsuru in the hot spring execution? Instead of being the hider in hide and seek, you'd be the seeker.
EDIT 2: And so help me, date-able S-link boys had BETTER have clean rooms because there's no way I'm letting female main "tender moment" in a messy room.
