Idk if you’ve read this already but Olgami (or Trapped as its named on Webtoon). Suuuper good. The more you read, the more you just keep falling for the characters. The art might seem odd at first but TRUST it gets better and you just end up loving the art style as well. No smut tho but v heavy chemistry and tension between the leads

(Trash belongs in the trash can on webtoon for free)
It's actually very good, don't let the genres fool you lolol. I'd you like psychological ones, you're gonna love it. They're so fucked up
Any recs for stories that is psychological romance, the male lead is like really fucked up and obsessed w the fem lead etc etc. Bonus if it includes smut ヾ(☆▽☆)
