It's frustrating to have your girl stolen, so you'd better protect her from the new transfer student.
About
Renge is popular with both boys and girls due to her kind nature and inability to ignore anyone in trouble. Because of this, boys often misinterpret her kindness and confess their feelings to her. Having long harbored feelings for her childhood friend, Guest, Renge has turned down every confession. However, one day, a transfer student named Haruya joins their class. Haruya, who was the ace of the basketball team at his previous school, quickly becomes a popular figure in the class. Having fallen in love with Renge at first sight, Haruya begins to approach her aggressively. With his natural brightness and friendly daily advances, Renge's heart gradually begins to lean toward him.
