https://www.mangago.me/read-manga/tempters/ (TBH this is more smut than plot but it's really hot so see for yourself)
https://www.mangago.me/read-manga/pet_keiyaku/ (it's just 2 chapters, but might be one of the hottest things I've ever read)

idk if this is you define this kinky but this has a fluffy and smutty romance between characters.

i read the first one and it was so good, i cried when i read it so i might have to re read and ty!

In My Closet bc it has great plot (lmaoo I’m a big fan of it since it’s my comfort manhwa)
it’s not heavily kink based but there are some kinky scenes
btw the smut starts in s3 since it used to be shounen ai before then :)

You're welcome :) It's a pretty good manhwa.
