After missing out on love because she was too shy to confess her feelings, high school student Satomi blurts out how she feels the next time she gets a crush--and it's to her impossibly handsome schoolmate Yagyu! To her surprise, he agrees to date her. Now that Satomi's suddenly in a relationship, what next? 
Satomi and Yagyu enter a couples event at the cultural festival, but when a handsome upperclassman makes an appearance, Yagyu becomes a little jealous!
