Yandere/Obsessive/Insane Love Interests/Semes || BL ONLY

Possessive - 3.5/5 (Wants to monopolize uke, but knows his limits)

Type: Possessive, “Soul Mate”
Summary: Crazy for you, but your well-being matters to me more than anything

It’s a bit weird when you start thinking that they’re cats during this whole ordeal, but cognitive dissonance will be your best friend! Overall, a decent read when you’re bored or looking for porn without (much) plot.

=AS OF CH. 50=
Possessive - 3/5 (Doesn’t let uke leave + gets jealous when people like him + created an orb in order to possess uke wholly)
Compromising - 4/5 (My man literally willed himself to grow overnight so uke could consider him as a romantic partner)
Obsessive - 1/5 (Thinks about uke leaving him 24/7, which feeds into his possessiveness)

Type: Desperate
Summary: You’re all that I have, so please don’t leave me

=AS OF CH.31=
Possessive - 5/5 (Broke uke’s legs so that he couldn’t leave him + monitors him 24/7)
Obsessive - 5/5 (Claims to be the uke’s #1 fan)
Delusional - 3/5 (Tries to act like the guy in uke’s story)
Crazy - 5/5 (Actually super violent, but acts like the guy in uke’s story)
Manipulative - 2.5/5 (Rewards uke for “good behavior” + possibly exploits uke’s desire to be loved)

Type: Confining & Mysterious

=AS OF CH.30=
Manipulative - 5/5 (Tricks uke into thinking his female crush likes guys who get penetrated + actively attempts to change uke from beta to omega to make him his)
Possessive - 3.5/5 (Would pair uke, but he’s not an omega, so he covers him in his pheromones + willing to biologically alter uke to make him his)

Type: Selfish & Manipulative
Summary: You’re mine, and I will do anything in my power to make it stay that way

=AS OF CH.2=
Possessive - 5/5 (Beats uke with a golf club when he tries to escape from him)

Type: Physically abusive & Confining
Summary: You will never leave me, and I will keep beating that fact into you.

This seme is straddling the line between yandere and straight up douchebag, so this manhwa may be removed from this list later on. I feel bad for the uke though since he’s stuck between two pieces of trash.

Possessive - 5/5 (Severs the nerves the ukes legs so that he couldn’t leave him
Manipulative - 5/5 (Made the uke think he was an omega when he wasn’t)

Type: Confining
Summary: I will make sure we have our “happily ever after,” even if I have to break you for it.

If you like a crazy seme and juicy tig bitties, then this manhwa is a must read! The seme thinks that the uke is his other half and is willing to do anything to make the uke his! I felt bad for the uke too.

Possessive - 2/5 (Wants to keep the uke to himself and away from other demons, that basic stuff; also collared him, but released him later to keep him safe)
Manipulative - 4/5 (Started their relationship manipulating the uke and continued the relationship doing so)

Type: Enslavement
Summary: You’re so pure, and I’ll make you mine.

A somewhat mild yandere, especially compared to the other semes on this list, but the dynamic (corrupt priest x pure demon) between the two are amazing!

Possessive - 3/5 (Ensures that uke doesn’t get with anyone else by interfering with his dates and watching over his activities over dating apps)
Obsessive - 1.5/5 (Thinks the uke is lovely no matter what he does)

Type: Persistent…
Summary: No matter what you do, I’ll always be yours, so be mine!

Rather than portrayed in a negative light, the seme’s possessiveness is painted as somewhat humorous. Plus, their chibi forms are so cute! A bit of a silly read imo

=AS OF CH.71=
Possessive - 5/5 (Just look at him, honestly)
Obsessive - 2/5 (Can’t get the uke off his mind)

Type: Confining
Summary: You are my lover and my omega, no one will take you from me.

It’s been a hot second since I last read this manhwa (‘cause of Zin Manga), but it’s still good. It’s practically a classic! One of the very first yaoi manhwa I’ve read, and I highly recommend it to anyone who likes yandere semes that develop as the story progresses.

=AS OF CH.45=
Kyung-hee:
Possessive - 5/5 (Refused to have anyone serve him but uke + got jealous of an investigator questioning him at night)
Manipulative - 3.5/5 (Makes uke repent for his part in the madame’s death by staying with him)
Persistent - 5/5 (Still wants uke after being pushed away + even married someone he didn’t like to get uke)

Type: Persistent + Possessive
Summary: You love and serve me, so stay by my side always

Everyone but Eunchae is so bad :’)
