Ichika, a stunningly shy girl, recently started high school but struggles to interact with others and form friendships. One day, Yuuya Yotsukado, a rumored ex-delinquent known for being "evil," surprises her with conversation behind the school. To Ichika's surprise, the two end up going to karaoke together. During their outing, Yuuya tells her that he wants to return something she dropped and proposes an unexpected idea. From that moment on, they meet for after-school strategy sessions to pursue their dreams.
