Since childhood, we've always been together and even went to the same school. Four of us, childhood friends, go to school together, spend breaks together, eat lunch together, and walk home together... I thought we'd always be best buds. One day, Meisa, who is bright and a mood maker, kisses the teacher… Itsuki and Karin, who witnessed it, were shocked. When questioned about it later… “I actually like him too,” Itsuki muttered. “Me too.” “What? Me too?” All four of them liked the same teacher. A middle-aged teacher… Who cares if it's against school rules, it's probably illegal… Who cares about appearances? The feelings of love in one's teens are overflowing with passion and not a shred of calm. Yuna, panicked, tries to monopolize him, but this time Itsuki and Karin can't just watch. The three of them fight over the teacher in a harem situation... Mei watches from afar… Later, even the teacher is called in for their first big fight. A ruthless battle of sex began to decide who would be number one. Who will be chosen...
