Perfect kiss: Nurashite playback.

Sayuri, who aspires to become a teacher, is forced to kiss a student while working as a private tutor, which is viewed as a problem by the student's mother. Through no fault of his own, he was lectured by his girlfriend's biological mother, who is a university professor, and was forbidden from becoming a teacher, so he took a job as a clerk at the office run by her mother. As a result, she spent most of her days with her mother, such as going to lunch or shopping, and she was given a fiancé arranged by her mother, leading to her living the life of an extremely boxed daughter. Still, he felt rebellious, and with the help of his cousin Rumi, he finally found an environment where he could live on his own.
