Aoi-sensei wa Shishunki

A high school student is secretly in a relationship with a biology teacher. The nature of their connection requires strict secrecy, as any public indication of their bond—such as messages, calls, meetings, or physical affection—is prohibited. The mere suggestion of their relationship could lead to its end. As a result, their emotions must be carefully concealed. The dynamic involves a serious educator and a student, forming a limited and cautious affection that unfolds daily.
