Nishiyama Hiyori (140cm, 4'7 ft at the start of the manga) has just entered high school after recovering from an accident the day before her entrance ceremony.
But, being as shy as she is, can barely introduce herself to the class. Once she finally works up to courage to do so, she is interrupted by Hirose Yuushin (190cm, 6'2 ft). It all goes downhill from there.
