▹ Harmless, Obsessive & Dependence Yandere.
▸ Hae-seo is pretty tame, he's like 40% crazy-60% cute. In short, he thinks Taewun (uke) & him are fated mates so he's relentlessly (𝘰𝘣𝘴𝘦𝘴𝘴𝘪𝘷𝘦𝘭𝘺) pursuing him. Hae-seo might be an alpha who turns heads but he only has eyes for Taewun; he dreams of him at night & thinks abt him all day long, follows him everywhere, jeopardizes his career for him. He even tries to guilt-trip Taewun into bonding with him bc he just can't live without him.
▹ Sadistic, Removal, Manipulative & Restraints Yandere.
▸ Choi Juhyuk is, by all accounts, a well respected businessman above suspicion--to everyone except Detective Doha that is, who suspects him to be involved in a series of murders. His instincts are soon proven right when he's captured by Juhyuk, who confesses he killed again & again out of love... For Doha. And out of love, he'll keep Doha forever even if he has to drug him, break his ankle or kill some more.
▹ Possessive, Self-indulgent, Overprotective & Restraints Yandere.
▸ Owen is opportunistic. When he finds Dylan squatting his attic, he decides to keep the boy. Why would he let a perfect sex slave go? That's all Dylan is to him until he ofc, catches feelings, goes murderous when Dylan escapes him but immediately calms down when he has him back in his arms. Dylan is then """""offered""""" to become a prized & well-cared-for pet under the 'fair' condition of never ever leaving Owen.
▹ Sadistic, Restraints, Loneliness Induction, Manipulative & Self-Indulgent Yandere.
▸ When his father remarried, Yoo-in met Seonghyuk, his new brother & favorite toy, one he breaks for fun but never discards out of love. Yoo-in's obsession is being indispensable to Seonghyuk & the cure to the evil he caused, so he deepens uke's loneliness to be his sole source of comfort (bc Seonghyuk should never be anything more than his), bitches him into an omega with heats ONLY Yoo-in can soothe, etc.
▹ Impulsive & Obsessive Yandere.
▸ Garam is not as malicious as other tops in this list but he's still pretty bad ngl. After being isekai'ed into the dating sim he plays 24/7, his goal is to force an impossible happy ending by winning over Tae-oh (the FL's dad). It starts with him using the FL to be close to Tae-oh then it quickly spirals into messy coercion territory. Garam can't handle rejection so he uses any strategy, like crying or getting hurt, for a chance to be loved back by Tae-oh.
▹ Kuudere, Possessive, Clingy & Obsessive Yandere.
▸ Angel is the perfect Kuudere/Yandere hybrid. He's so emotionally stunted & distant that he believes his growing fixation on Guster (uke) is just a natural part of his research. Repressing his love for Guster only makes Angel more dependent & obsessive, until his jealousy completely consumes him & he nearly destroys the whole world when he becomes the Demon King-- all this over the mere THOUGHT of Guster being with anyone other than him.
▹ Self-Indulgent, Delusional, Obsessive, Manipulative & Sadistic Yandere.
▸ Heewoo's love for Kangil (uke) is selfish & irrational. Kangil is drowning in debt bc Heewoo's father ran off with his money? Who cares, Heewoo will repay it so Kangil should just be grateful & move on. Kangil doesn't care abt him anymore? He'll blackmail & break him until he does. His wife left with the kids? Then Heewoo will be his family now, son & husband all in one. There, problem solved! Just insane & greedy.
