Yukihime is a 3rd year and is going to Shiketsu High along with her best friend Camie. Camie is the one who introduced Yukihime to Seiji, and ever since that day, Seiji and Yukihime hang out.
Seiji has developed feelings for Yukihime and goes for Camie for help. She agrees and starts coming up with plans for him to confess.
Yukihime is kinda of clueless, so it's kinda of hard for him to be blunt about his feelings. So he thought about having Camie helping him. Not knowing that it's going to be hard for him to literally confess to her. Yukihime has a crush on Seiji and tries to come up with ways to confess to him as well.
In the end, they confessed and felt relieved.
