It's their final year of high school. Gaku's one-sided feelings for Haru, which he'd kept hidden all these years, have begun to stir. They'd been friends ever since high school began, and they thought that their relationship would never change. They would hang out with girls from another school, focus on studying for college entrance exams, and take a breather at the school festival... "I love you Haru." With the confession, their world would change. This is a year of a normal student life in which best friends who were always by each other's side become lovers.+
