Ikenai Hito

Shiraishi is a middle school teacher who is fed up with everything. She was dumped by her longtime girlfriend, and she hates her job. Every day she deals with bratty students and their irrational parents, and today was no different. She was making her usual rounds to her students' homes to speak with their parents, as she approached the last house. Here we go, another crazy parent...she thought to herself. But the woman who came to the door was...beautiful, calm, and extremely her type.
