Ok, guys I'm going crazy cause of this manga i read that i cant remember. I remember only few things about it.
-the mc is a long, dark haired guy who works for the emperor who has braids. He gets nauseous around blood, something to do with his work. Mc is also said to be gloomy. His relationship with his dad growing up was bad. i think his job might have been stigmatized.
-u hate the dad for being neglectful at first but then realize he had started to try.
-librarian character.
-emperor hated being an emperor and only liked to invent stuff.
-there r soldier characters that might be twins,im not sure
-lots of cute guys.
-might have been a war-like arc.
-most of the conflict that happens r resolved as accidents. His dad was said to be murdered but it ended up being a boomerang or something like that that the emperor, at that time prince, threw.
-i might have found it on forums or category searches related to "royalty" or "androgynous male lead."
-manga has very good arc
