TW: Rape (by ML and later with others) and Drugging (later with others)
Girip is possessive and obsessive over Pyoeum to the point by the end of S2, Pyoeum pretty much has stockholm syndrome.
Officials are here, so hopefully a season 3 is here
Art is extremely pretty.

Tw: BDSM, confinement
Yishin Kwon is 100% obsessed with Yoohyun Jin (to the point that he keeps him confined with a chain. However, unknown to Yishin, Yoohyun really likes Yishin and everything he does, but pretends to not like it cause he thinks Yishin is actually from a bdsm BL novel, and thinks that's how he needs to act). Both of them talk through everything and get their happy ending

Tw: confinement, rape, murder (in the past)
Uriel is a mermaid who is extremely possessive and obsessed with Felix, and Felix's past life, Derek. To the point that when Felix finds out the truth, he keeps Felix confined for a short time.
They do work out the issues they have and Uriel works through the fact that Derek is gone and Felix is his own person, and not Derek.

Tw: BDSM, violence, self harm
Hwayoung is a sadistic dom incredibly obsessed and possessive over masochistic sub Gyuwon (Gyuwon is also an ex-mercenary and super buff). Possessive to the point that he would kill Gyuwon then himself if Gyuwon ever left him for good.

Tw: rape, kidnapping, mpreg, tentacles

Tw: Coercion
Seojun broke up with Seunghyeon 3 years prior, due to feeling inferior. 3 years later, Seunghyeon finds Seojun again, pays off his debt, and coerces Seojun to sleep with him again, and work with him again on an acting gig. IMO, I think everything got swept up and resolved a bit too quickly, kinda wish it had more chapters to flush everything out, cause Seunghyeon still likes Seojun, and Seojun realizes he still likes Seunghyeon (even with the coercion). Meh

Tw: Abuse, sexual violence, confinement, violence
Heesu and Saha are literally both obsessed with each other by the end, and both can get jealous incredibly easy. For a while, Saha cross dresses as his sister cause his sister was supposed to be in an arranged marriage with the elder brother of Heesu, but ran away before she left, so Saha's grandmother sent him instead.

Note: uploads end at the end of S2, will need to read the rest elsewhere (highly recommend, the story is good)
Tw: abuse, child abuse (flashbacks), sexual assault, drugging, rape
Seungho is completely obsessed and possessive of Na-Kyum (even before he really realizes it). He does do some things that are not OK to Na-Kyum, before he gets better and treats Na-Kyum better.

Tw: Rape, confinement, drugging, violence
This one was meh. I wish I liked it more, cause I know I did when I first read it, but now I'd say it's more mid. Gyuh-Wool is obsessed with Jinyoo to the point he kidnaps and confines him while planning to get revenge on the people that wronged Jinyoo.

Tw: kidnapping, rape, confinement, violence, sexual violence, suicide attempt (flashback and present)
Sungho is very possessive and obsessive when it comes to Dohyun. And by the end, both realize they can't live without one another.
I like the ending to this one because it's not completely straightforward as some stories are. Relationships can be messy and can hurt (in this case as an extreme), but that's what makes people human.
