This is gonna be so hard to find but i'll take my chances.
To my novel reader girlies/boyies I NEED to find it.
It's a bl novel.
-it's about a guy reincarnated in this novel/or a new world.
This world contains various species such as beastman.
-he finds out that he has been reincarnated as the villain prince who was a racist fuck and mistreated beastman
-his mother is also the root of his stupidity as she would always support him through his spoiled roots.
-he was an illegitimate child and was pretty much abandoned and hated in the royal castle
-he had 3 brothers that came from the first loved queen, his mother was a concubine at best.
-i'm not exaggerating when I say that they all hated him except his mother.
-his first brother was an angel lover freak that had connection with the priest
His second brother was a tsundere, as the story develops you'd see why
His third brother(the youngest) was a sweetie pie and was only influenced to hate him but was the first one to forgive his insolance
-the prince he reincarnated into had blond hair and despite their hatred, netizans called him the most beautiful prince of the empire.
-there was a general (the ml black hair) who hated him the most but I think he was appointed as his guard and that's how they became close. The general was a beastman but it was a secret revealed into later
- the mc soul switched and woke up in a bed while his mother (the concubine) was crying besides him after a so-called accident where he fell from his horse.

- the whole goal of his life is to now try not to get kicked out of the castle, get a redemption in the eyes of many people who hated him
-he falls in love with the general first but the general falls harder(the mc was always gay and the general was his type lol)
Pls help me find it.
!hint! The title starts with "I reincarnated into/as the"
This is all I can remember but it was such a good novel!!!
