Anything with good art, toxic seme and clueless uke but seme gotta be sexy... doesn't matter if it's ongoing

I left this in the middle cuz i like semes that are toxic not stupid （/TДT)/

"Cry Me a River" is starting off pretty good. There are only 7 chapters so far but the seme seems toxic, he's handsome and rich.

"Kiss Me Liar" was a frustrating read. The seme's looks are subjective but most would say he's hot, toxic, and objectively rich.

"PLACEBO: Let's Play" is still ongoing. It currently has 19 chapters. The seme is hot and manipulative. He uses hypnosis to control his step brother.

I'm just going to list them off now.
• Waterside Night
• Painter of the Night
• Black Mirror
• Dispar

Here's a great list for ya as well:
