Literal God's Manga

Pretty funny. Read free on bilibili. They have a great app and some other really good series.

I love this. Such heavy topics though, so not for everyone.

Warning that the seme in his past life abused the uke in every way. The reasoning behind that is still vague at this stage, but we do know that there is a pretty crucial difference between how Jin and humans socialise and that violence is pretty normal for Jin.

We also know that neither Jin nor humans are aware of these differences (as sometime in the future they write a guide about it).

So at the moment it looks like the original emperor had no idea about humans and had no idea what he was doing wrong. The uke had no idea why he was being hurt and why the emperor didn't care and even seemed entertained at times. The original emperor likely realised something was wrong, but not what it was, so probably became more aggressive with the building frustration. The uke rightfully withdrew further in response which only increase the frustration and it became a viscious cycle of destruction. That's my best guess at this stage.

I really want to know why he ended up poisoned though. Maybe he wanted to weaken himself so the uke could kill him?

Regardless, the current emperor has had human socialisation and isn't abusive at all towards the uke. So it's not a case of the uke falling for their rapist if that's a concern. It also treats the trauma with what I'd consider appropriate respect.
