Ouji-sama Sama no Jijou.

Kagami has always enjoyed a comfortable life as one of the most popular boys at school, admired by his peers and seemingly without a care in the world. However, his carefully maintained image is suddenly thrown into jeopardy when Tsukishima, the formidable and widely feared president of the anime club, manages to uncover a deeply guarded secret he never intended for anyone to learn. The revelation leaves Kagami completely horrified, as the exposure of this hidden truth threatens to dismantle everything he has built. Rather than immediately exploiting the situation for her own amusement, Tsukishima offers Kagami an unexpected proposition. She agrees to keep his compromising secret entirely under wraps, but her silence comes with a steep price. In exchange for her discretion, Kagami must fully submit to whatever terms she dictates, placing him directly under her control. Now trapped between the fear of public exposure and the demands of the intimidating club president, the popular boy finds himself navigating a tense and unpredictable dynamic where obedience is his only option.
