obsessive? obsessed.

platonic yandere harem is a-go
the MCs brother is the main yan so far- he’s overprotective & a lil possessive. he has a few “I should lock you up and break your legs so you stop getting hurt and leaving me” monologues (novel) but the MC works thru it with the power of open and honest communication !!! most of the other characters are also very attached to the MC & are super protective of him.
—also has a novel & a webtoon! the novel

no longer a promo!!!
the ML is an obsessive slave turned OP mage who kills the FLs family (who abused him!) and then kidnaps her & confines her to a tower so she’ll pay attention to him
—also has a novel!
TW: blood & violence, slavery, child neglect & abuse, domestic violence

classic “my spouse used me as a replacement for their first love and treated me like trash, but now I’ve reincarnated and I’m kicking their ass to the curb… wait why are they in love with me now? SCRAM!!!” plot
note: blonde ML has began losing his marbles. the yan has seemingly begun :)
—read on bilibili to support the author!

the MC is a poor author/shadow writer living in the slums. when his neighbor invites him over to eat dinner, he discovers a corpse in his back room, and now he’s gotta deal with his serial killer neighbor trying to date him
blonde ML is batshit - extremely obsessive, stalks the MC for years, murders people, etc etc
multiple yandere-esque side characters
plenty of murder, stalking, and obsessive monologues :)
—also has a novel!

more chapters available on manta :)
another dungeon gamelike. MC can fix the damage caused by dungeonbreaks, but only takes small jobs. the ML is the leader of a big guild & trying to recruit the MC (via unethical methods sir this is a wendy’s).
MC seems like he’ll be obsessive (&maybe possessive), but there’s no explicit romantic stuff yet (imagine somebody stalks & forcibly recruits for ur ability to fix stuff, not even ur personality ) smh

ML has baby yandere vibes (possessive, abandonment issues)
secondary ML (blonde fuckboi) also gives off sus vibes
MC transmigrates into a novel as the master of her favorite character (ML). she fangirls over & dotes on him (super cute sappy stuff) and the ML gets closer to her.

most lists say this is yandere but I haven’t read it yet so take it with a grain of salt

technically yandere IMO
ML seems obsessive (but has that stone cold pokerface & childhood trauma)
basically MC is a mercenary who encountered/saved(?) the ML when she was a soldier. MC is tight on money & conveniently applies to the bodyguard position of the ML. ML later winds up getting her to sign 10 year/lifetime contract (always read the fine print) & uses her position as his bodyguard to observe her.
