It's a fantasy manhwa where a dude that helped kill the demon king had a crush on this long haired blonde guy that he thought was a woman at first and after they kill the demon king he's broke and needs a part time job and he happens to find one where he essentially gets fucked by fantasy creatures while said blonde guy takes note and whatever else happens
