Wasn't sure how obsessed you were talking, cause I feel like most semes become obsessed at a certain point. These are the most obsessed guys I could think of, like genuinely leaving is not a choice the uke has.
The abyss - ongoing, art is pretty bad but the plot had me catch up in one night. Genuinely more of a psychological thriller
A tree without roots - ongoing, there's a time skip, uke saved seme as a child and it lowkey (highkey) altered semes brain chemistry
Regas - ongoing, this one made me cry in the first half, but it's also very funny
Roses and champagne - complete, I love this one, but what the seme does to make sure uke wont leave is absolutely diabolical
Salvation spirit - ongoing, doomed from the start. I wont spoil anything, but this guy is the worst of the worst
The rouge prince is secretly an omega - ongoing, abo, actually really sweet, but the uke still doesn't have any option of leaving him. I fear what he would do
Unfinished business - complete, absolutely sick this obsession is more of a revenge
Mad dog - complete, no smut until side stories, love them so much, seme is definitely crazy though. The things he does to get uke are wild

green flag - treats the uke right despite the obsession
yellow flag - mixed signals abt treating the uke right but also lowkey toxic bcuz he's obsessive
red flag - treats the uke trash at first then only treated them right bcuz they became too obsessed yet still toxic
black flag - literally traumatizing type of obsession
well passion's seme (ilay) can be counted as black flag but for me he's red flag because he didn't do much as what champagne and roses' seme (caesar) did to the uke...
Recommend obsessed semes please!
