Wow. I thought he was more like a Loli-bait boy. But it's not unusual for boys to be dressed as girls until the reach of a certain age. A lot of cultures believe that it builds character in the boys. In the US even one of the president's was dressed as girl when he was child. In some parts of the Japanese culture and in a lot of Korean culture it's still practiced. But if he looks like a you slut that may have more to do with that face of his rather than his dress. That face just screams femboi, or uke.
He dresses like a slutty femboi because he IS a prostitute. It's mentioned in chapter he worked in a brothel before being transferred to the Palace.
Doesn't make him a slut. Working as a prostitute in a brothel doesn't mean he's a slut just a prostitute.
Who are they kidding?
I don't think he bats for the team where procreation is possible unless its an omegaverse lol. The "candidate" looks and dresses like a slutty uke from a fantasy Yaoi smut.
Something tells me he wasn't servicing female clients at the brothel where he worked.
