Kanzaki Riri, the new girl in class, has a peculiar pastime - she wants the school’s toughest delinquent, Atsuko, to say ridiculously cute things. Atsuko plays along, thinking Riri’s just a harmless weirdo… until those silly little word lists start making her cheeks turn red. With each sweet phrase, the gap between them closes - and it’s not just Atsuko who’s getting flustered. Is this just a quirky game between opposites… or the beginning of something real?
