Not really. The main pairing only has sex with each other but I should mention that they don't have a relationship. They've become friendlier with each other and we got a little bit of backstory but there was no real progress.
The other two guys are still just friends although we now know that the guy with the short dark hair actually has feelings for purple/greyish hair guy but for some reason they're just friends (that hasn't been explained yet). Which also means the purple hair guy has sex and dates other people but there's no real love triangle.
However, it's still mostly kinky sex scenes and not really plot heavy.

Hey guys did the author drop this manhwa? I hope it wasnt,
