About

Leo once formed a harem, receiving affection from Misaki, Yui, and Kana. However, when Leo started dating another girl, they accepted their heartbreak and naturally drifted away from him. Yuma was the one who comforted them while they were feeling down. Yuma listened to their troubles, and as he stayed by their side, they all fell for him, eventually leading to him dating all three of them. Eventually, Leo's girlfriend had to move away due to her parents' circumstances, and they broke up. Leo tries to reach out to Misaki, Yui, and Kana, but not a single one of them has any lingering feelings for him. Furthermore, he learns that their current boyfriend is Yuma. Faced with the fact that "the girls who used to love me all chose Yuma," Leo is consumed by intense jealousy and rivalry, and attempts to steal them back from Yuma. Well, it has nothing to do with Guest and Hina, though.

Well... maybe I'll invite Misaki out for the first time in a while.

He thought she would obviously be happy if he reached out to her just like before.

But—
