Chiyo is too oblivious and kind for Kiyoshi. Hana, may be a bit crazy but it is because Kiyoshi always end up seeing her in compromising situations. He has seen her pee, peed on her, and had his mushroom touch her thighs, finally he saw her medusa and humiliated her further by calling it that. I really feel bad for Hana, but her being a sadistic b---- got her in that circumstance. I think she's got to be a bit of masochist though if she gets turned on by being humiliated. I think a relationship between her and Kiyoshi would be unusual but interesting to see but I hope she doesn't rape the guy. Because rape is not cool.
Also, wtf vice pres!!! Who suffocates people with their crotches!!! Insane!!! Is the president's click all a bunch of sexually repressed women with strange fetishes?
