Something like Zhu Xian My Fiance is in Love with My Little Sister Heaven’s Shadow Death Sutra 转生成精灵的我不想当宠物 尘缘 Translated/untranslated No Yaoi/shounen-ai No modern day/future
Abuse = you mean BDSM stuff ? or a really crappy life full of problems for MC (author abusing him/her) ?
I'm not sure if it continues, but the first chapter of the manga was pretty abusive. My Sister Told Me to Give Up My Fiancé
I was going to call you names to poke some fun at you, but now I'm pretty sure that would just get you off If I may ask, why? What makes this topic so attractive to you that you actually put in effort to look for more of it?

MC keep being betrayed, and kinda insane in my opinion. I like how cruel and insane he is) - Kingdom's Bloodline (You can read it at Webnovel. The author of this novel really like child abuse. How could he did that to MC?! MC is in child body, with no golden finger, in an unknown world. Keep being betrayed by his father, loli, bystander, etc. I keep reading because I am curious about this world setting and how MC will grow into) - Re:Zero Kara Hajimeru Isekai Seikatsu (I don't know whether you like JN or not, but maybe you can try this.
