寝取られの教壇 ～教え子に奪われた愛する恋人

Two years ago, teacher Hayasaka Jo decided to date student teacher Minase Saki after she confessed her feelings to him.
The two slowly grew to love each other.

Time passed, and Saki, now a teacher, was hired at the boys' school where Hayasaka teaches, but
they kept their relationship a secret from those around them, intending to maintain a relationship as superior and subordinate until they got married.
