This is what I remember:

The uke worked for and was brought up by the seme in what looked like the yakuza. The uke does or is involved in something and gets the seme mad. Uke decides to leave but the seme finds out and rapes him. The uke continues to stay with the seme.

I remember one scene where they're sleeping in bed and the uke is having a nightmare about the rape while the seme watches. Also the seme has a daughter with a divorced wife who at one point kidnaps the uke.

Is it Ikujinashi no Shiawase second story?

Yes! that's the one. Thanx 😀
