omg i adore this one. like mc Jin in his original world wishes to get some bdsm action yh? so he gets migrated into this novel where the secretary gets kidnapped by their psycho boss Mr Kwon. and like throughout the novel the secretary guy gets bdsm stuff used on him to make him submit but ofc Jin is into ts so he gotta hide the fact he aint the original secretary and enjoy his stay at the same time lol.

I really adore this one too but its been dropped sadly. our mc Lucien(? i haven't read this in a while) is reborn into this fantasy game as a npc and basically changes the stories of all the villains and forms a harem . my memory is hella rusty but i remember his first is the werewolf boss virgil. we find out hes only hostile in the main game because humans killed his sisterand he has a distrust for the whole species, Then the dryad boss. i really love his design. his skin actually looks like tree bark and mc saves him from a slave trade which made him hostile in the main game. i don't really remember his story much but its a vampire and mc kinda helps him w his passion for dress making and we get some yummy crossdressing scenes. and then i think the last is the fae king. I love his hair, its all fluffy and whispy like a cloud and i love the detail they make him wear a bonnet to bed. anyways i'm rambling now.very fun read

Some transmigration/isekai bl recommendations?
