Yuzuru is not very popular in high school. Despite his beautiful face, his closed personality prevents him from making friends. If he goes home as soon as classes are over, it's not for pleasure but to take care of his sick older brother. Now, after many years, he reunites with his childhood friend, Kotarou. Being open and friendly, Kotarou doesn't hesitate to invite Yuzuru to hang out with him and his friends after class, in spite of his constant protests. Worried about his brother, will Yuzuru choose to repel or seize that hand?
