When studious Nariyuki tutors two supergeniuses who are total dunces in their favorite subjects, he'll get a crash course in love!

His principal agrees, with one stipulation-he must tutor three of the most talented girls at school and make sure they get into their target colleges! Mafuyu Kirisu is a strict, no-nonsense teacher who has dedicated her life to helping her students in academics. She has always been dismissive of what she considers hopeless dreams that hinder academic progress, but after meeting Yuiga, she's slowly changing the way she thinks. What stymied her own childhood hopes and aspirations?
