"A Tree Without Roots" is amazing. "Missing Love" (this is a but traumatising though)
"Red Mansion" (but they're both crazy)
"Even if you don't love me" (also amazing but traumatising)
"For my Weirdo", "Unfinished Business" (this one is an omegaverse.)
Almost forgot "Formless" which is very similar to what you're looking for
sadistic beauty bl side story
BL manhwa
Plot
Seme straight up abused and raped uke, keeps him in a chain etc, but when the uke finally got away, the seme realized what he truly feels and run after the uke and proved that he will change and he make the uke fall for him sincerely
In short I want to read a manhwa of from a seriously messed up relationship to healing their relationship
(I recently watched the Thai BL series Love Syndrome and I kinda want to read a very similar Manhwa)
