so I cant remember if it was a manhwa comic or hentai, all I know is that the characters were faceless, the panels were colored, and the girl cheats on the guy before the wedding and they have sex at a hotel, the guy is like an artist (the one she cheats with) and the girl is the model, she lets him cum inside and after all that she gets married with her bf and let's him cum in her mouth. Good luck ig
