Tsukamoto tries to leave the girls' bathroom without Harima, who is standing right outside, from seeing her. I don't know why this is even a situation. I guess it's like how girls don't fart in public, I dunno. So yeah, she decides to wait it out, after all, he's only talking to friends. Thirty minutes later, he's still out there, only now he's reading a book! Tired of waiting she decides to disguise herself in toilet paper. She does other stuff too. It ends with her scaling the wall outside the bathroom. Of course, like the Road Runner, Harima is there to meet her at the bottom.
Each show is split up into three vignette, that's only one of them.
