Nano Saikawa is a young popular high school teacher with only two problems. The first is that she is single, and the second is her own student, Soji Kuga, who is causing her a number of inconveniences. While Nano promises her acquaintance will take care of the first problem by arranging a blind date with him, not even a higher power can cope with the second: because Soji is more relentless and stubborn than any creature. Disguised beyond recognition, he is presented at the tryouts as the groom-to-be, and Nano approves of him at a glance. It would be all right, but the deception is quickly exposed, and with it Soji's true feelings. Will Nano opt for the wayward apprentice, or will he fence off the wall of impregnability? And is any relationship possible between them at all?
