Doki Doki School Hours (2004)

A very short 27 year old teacher has an interesting time trying to teach her class. She has to deal with the eccentricities of her students as they present themselves over the school year. When you have an insane class (which includes a cross-dressing narcissist, an otaku, a dumb jock, a boy-band obsessed girl, a lesbian in love with the teacher, a homosexual in love with the jock, a guy who looks like a middle-aged man, a girl obsessed with material items and the vain rich girl), what's a person to do but hope?
