for manhwas, i’d recommend hate mate (do take note that there’s a love triangle though so id opt out if that’s not your thing), food chain, in the private room, jueun, limited run, dear teddy bear, and the perfect relationship. for mangas, these aren’t really toxic but they do fit the age gap bill: flip flip slowly, i didn’t mean to fall in love, mobsters in love. for novels, i really like chinese bl/danmei but ik they’re kinda hard to find so you’re gonna have to browse through and do ur research but accidental mark is a good one

pleasee recommend me some bl or bxg which the leads have a huge age gap (older top), with a good plot, slow burn and less smut is even better
tia!
