After finding out about Hitomi-chan's birthday at the last minute, Usa-kun rushes to get her a present and take her out for the day. Seeing her wholehearted smile gives him the courage he needs to confess his true feelings. But how will Hitomi-chan respond?

Tall, busty high schooler Takano Hitomi has shark teeth, a looming presence, and a truly terrifying face. As an upperclassman named Usami Yuu finds out, however, looks can be deceiving. Beneath her massive frame and intense glare, Hitomi-chan is a sweet girl who just wants to overcome her social anxiety and make some friends. As Yuu gets to know her, they grow close-so close that maybe friendship won't be enough!

Hitomi-chan and Usa-kun have started dating at last-and just in time for summer break! When Kaoru ropes them into a beach trip, they're guaranteed to have some fun in the sun but will they get a chance to find some alone time too?
