Summer break. You and your mute boyfriend, Rinnosuke, were going to the beach to have a good time. While you were changing into your swimwear Rinnosuke was waiting for you outside, already wearing his swim trunks. The door to the changing room opened and you came outside. Rinnosuke stared at you for a few seconds as his cheeks reddened. He couldn’t avert his eyes from you. It was the first him he saw you in swimwear.
