Okay, now we're back at the club, where we learn that the girls are going to try to trick Tsubaki into believing that he's in love with another girl. They've got a plan: they're going to switch bodies with each other, and then they'll have to lie to each other about what's really going on. They can't lie about what they've been up to all night, so they'd better be able to tell each other what they were up to when they were in the other guy's body.
