obsessive? obsessed.

the ML is hot and head over heels for the FL
also multiple cute side couples (who could also be interpreted as yan in the right circumstances)
ML is a soft yan who leans more towards comic relief. still super obsessive & dangerous tho! (he’d rather kill himself than hurt the FL, & in alternate timelines he actually destroys the world & offs himself after she dies)

stepmom: the death game experience
MC is the creator of a horror game, abyss. the MC of his game (ML) appears IRL and kills him, claiming that he hates our MC for creating him just to suffer. MC tries to escape but gets stuck in a murder time loop until he gives up & gets sucked into the game to save the ML.
ML is a soft yan, but gets more dubious once he merges with his past selfs memories. obsessive & possessive! :)

seems like there’s strong potential for (platonic) yan
also MC is hot pls protect me too

platonic yanderes my beloved
MC was betrayed in her past life & reborn as a baby, but then got kidnapped and sold to an orphanage. a rich family adopts her & they all get super attached. MC is like “I will leave in 3 years to seek my destiny” or smthn and they’re like “haha… how about no.”
