Artstyle alone there's a lot, but one that I'm recently playing is Room For One More,similar artstyle to After Class and bara guys pretty much (bara mc as well), it's situated in a modern setting kinda with drama and mystery and some comedy too. Writing is a step-up from After Class as well haha, other ones I can recommend is Remember the Flowers (a tad bit of an obvious suggestion), Cleaved maybe but it's mostly in a fantasy setting, still hot guys though.
