Stuck in My Sister's Dating Sim
So MC gets sent into his sisters dating game and goes into the body of an obnoxious and bad side character. He is the character who helps turns the villainess (his cousin) evil. But then he dies. In order to avoid this he is nice and tries to change his image. But the villainess is currently engaged to the crown prince and the prince falls for our MC and it becomes a BL. There is an evil duke who is 2nd? lead in the game and he also starts liking MC. MC can neutralize his mana. One day MC gets drunk and they are all at the academy and the Duke gives him hickeys all throughout his body. Then the price sees the hickeys while MC is sleeping and gives him some too. RN the prince confessed to him but MC rejected him. There is also another ML that is half beast which the MC saved and now the beast vowed to always protect him as the head of the imperial knights. It seems MC is reacting to the black haired duke but not the crown prince. Also the original female lead is in love with the villainess
