PRIDE BLUE -Ore no Aishita Hokoritataki Reijou wa Chichi no Shihai no Naka de Ochiteiku | PRIDE BLUE ～俺の愛した誇り高き令嬢は、父の支配の中で堕ちていく～

The stage is the prestigious private Ryuka Academy. The protagonist, Yuma Shinonome, is the student council president and son of the academy's director. The Shinonome family has run the academy for generations, leading him to be seen as "unapproachable," and he has no close friends.

The only special person for him was Reina Sakuramiya. She also attends the prestigious academy and is the daughter of a wealthy family with a distinguished lineage, but she is often ridiculed as "nouveau riche" and gossiped about behind her back.

As a result, she doesn't try to get close to anyone and is an outcast in the academy. She is seen as a troublemaker, but she seems to be at odds with Yuma, yet they somehow understand each other. In fact, Reina was beginning to be attracted to Yuma, who "persistently bothered" her.

Meanwhile, Tokuma Shinonome, the academy's director and Yuma's father, outwardly pretends to be a gentle person, but behind the scenes, he arranges sex escorts for the financial world and celebrities, building his power.

One day, Tokuma, who is unhappy with the relationship between Yuma and Reina, warns Yuma, but this escalates into an argument, creating an even deeper rift between father and son.

Then, in order to teach his impudent son "reality," Tokuma chooses Reina as the next candidate for the academy's prostitute.
