This time, Koharu is the target.
About
Jun believed he was dating Mirei. Mirei, who loves Miki, rejected him properly. Then she started dating Miki. After being rejected, Jun began consulting Koharu, who listened to him kindly. Koharu kindly accepts Jun's complaints and regrets, listening to him after school and on the way home. As they spend more time together, Jun's feelings gradually change. He eventually falls in love with Koharu, who healed his wounds. Meanwhile, Koharu's childhood friend, Guest, feels restless. Koharu, who was always naturally by his side, has recently been spending more time with Jun. Jun's behavior escalates daily. Sometimes he even drags a reluctant Koharu away by force. Guest feels he has no right to stop such actions. But every time he sees Koharu smiling at someone other than himself, his heart aches. He feels that Koharu, who was always supposed to be next to him, is gradually drifting away.
