Help me find title pls

It’s an old yaoi manga.
It’s a one shot and is part of a one shot collection.

Plot: Historical yaoi, where Uke was once part of a royal/elite family. The Seme’s sister worked for Uke’s fatner, and Seme was assigned to take care/babysit the Uke when they were young. Sadly, without the Uke knowing, his father was a sexual predator, and SA’d the Seme’s older sister (and other household maids). After this, Seme’s sister unalived herself and Seme swore to take revenge on Uke’s father.

Fast forward to the story, the Uke’s family name and wealth have all been tarnished, and Uke’s mother has fallen ill, so Uke had no choice but to sell himself. Unbeknownst to the Uke, it was all the Seme’s doing as a form of revenge.

Seme actually loved the Uke but was blinded with revenge, so he continuously paid for the Uke to spend time with him and humiliating the Uke as revenge.

That’s all I can remember help me find it pls
