I read a manga a long time ago and I'm pretty sure it was an isakai bl with bdsm and an alien uke. The seme had to bully the uke because he was the villain of the story and the uke secretly liked it. The seme ended up being banished because of the bullying and the uke ran to find him believing it was part of the play and eventually confronted him in a stable or something.

Sound like it was this,
Although it was the uke bullying the seme.
I'm looking to read some good bl that will leave me a sobbing mess and wanting more. I'm in the mood for a good crying session ( ╹▽╹ )
little mushroom (the novel)
These are the only 2 times I've cried:

Even if the novel wasn't sad, the translation was so beautiful that it would have still brought tears to my eyes.
