Very Private Lesson

Oraku finds himself in a rather precarious situation as a high school teacher with a seemingly idyllic life. He harbors feelings for Satsuki, a colleague he aspires to marry, while also attracting the attention of Aya, a captivating student who has developed a crush on him. Complicating matters further, Aya's affluent father, a powerful crime lord, insists that she live with Oraku to ensure her happiness, placing an immense burden on the young teacher's shoulders.

As Aya's affection for Oraku becomes increasingly bold, often leading her to lounge around his apartment in revealing attire, he must navigate a treacherous landscape. Not only does he face the challenge of maintaining his professional integrity and keeping Aya safe from unwanted advances, but he also risks dire consequences if their arrangement comes to light. With the threat of Aya's father looming large, Oraku's luck may soon run out, pushing him to balance his desires with the need to protect both his career and the girl who has unexpectedly turned his life upside down.
