Do you know of a manga where a guy uses blackmail to get close to someone?

I would appreciate it if it was a romantic comedy. idk
It has to be a completed manga series, meaning I don't want to have to wait for the next chapter.
You MUST include a summary!!!!

Thank you so much for all of your help, I am very greatful.

Hot Gimmick

"The story revolves around Hatsumi Narita, a passive sixteen-year-old girl who lives in a company housing complex that is ruled by the tyrannical Mrs. Tachibana, the wife of the company's vice president. How a family behaves in the housing complex can affect an employee's status in the company. When her promiscuous younger sister Akane thinks she might be pregnant, Hatsumi gets talked into buying her a pregnancy test. Unfortunately, things don't go exactly as planned and Hatsumi is blackmailed by Ryoki Tachibana, the arrogant teenage son of the powerful Tachibana family who bullied her as a kid, into being his slave."

Really good series. One of the only romances I've truley enjoyed. Miki Aihara is a great author.

When Hatsumi has to buy a pregnancy test because her popular sister Akane is late, Mrs. Tachibana's son, Ryoki, who used to bully Hatsumi as a kid, promises not to tell the world about Hatsumi's secret, only if she becomes his slave.
