I don't really read dark bls so idk what classifies as one but Cozy Obsession might be an ideal read? It technically doesnt have SA but you'll understand what I mean by technically. https://www.mangago.me/read-manga/cozy_obsession/
Have you ever tried https://www.mangago.me/read-manga/dreadful_night/ or https://www.mangago.me/read-manga/fate_makes_no_mistakes/ ?
Also, cozy obsession is fire

I think this had a love triangle in it BUT PLEASE give it a chance same author as release your persona. And its completed

Hellooo, can anyone recommend me dark bl manhwas that absolutely have zero SA or cases. I just want them to explore mystery or normal revenge bc of some bullying or something. I don't want any of them to have experienced getting assaulted js "for the plot". I'm pretty tired of all these bottoms (especially in popular bls) always going through this :(((. And no love traingle too.
