Even though she is a teacher, Mai Morisaki's character is quite...special: self-demanding, impulsive, and selfish. Will she be alright when she moves in with one of her students, Nishimoto Daisuke? They get along perfectly at first, but to be honest a man can stand only "so many times" seeing a woman in underwear and doing nothing... And even with that, Mai is the one who ends up making "the first move." Will this bold relationship remain hidden from the school students? Or the self righteous vice principal who happens be charmed by Mai? (Source: MU)
