Synopsis:
Sakuma Mitsuki is a second-year student known as a beauty in the entire school.
Although her school prohibits romance, a trivial incident leads to her getting an ordinary third-year boyfriend.

The day before her boyfriend's entrance exam, Miyata, a playboy who Sakuma has rejected, appears in front of her.
Miyata threatens the two with the evidence of the romance ban and forces Sakuma to have sex with him. With the possibility of expulsion in sight, Sakuma accepts Miyata's proposal in order to protect her boyfriend.

Miyata, whose pride is hurt by Sakuma, mercilessly humiliates her and leads her to succumb to pleasure...kind of classical cuckold though I really like it.

What school bans romance? And why not blackmail him with recordings of them actually having sex?

So, did the playboy demand to fuck his girlfriend in the MC's bed or is that the playboy house? Either way, it was a tremendous humiliation.
