"If you gonna be that kind, I'll fall in love with you, teacher."

Itsuki Ichigoharaーa married woman in her late twenties. Occupation: high school teacher. And yet, she made a move on a female student ten years younger than her. The student's name is Rin Togawa. She's tall, gentle, kinda childish, and pretty. And she's a really nice girl. While Itsuki was concerned about Rin, who had problems at home, they ended up kissing in bed. This is definitely a betrayal, an affair, a crime. How will Itsuki get through all these elements that could bring about her downfall?

"How did it end up like this?"

Lustful and unfaithful but somehow warm. A love story between a female teacher and a female student.
