From what I can remember is that the mc had red hair and I think was reincarnated as a villain illegitimate child prince(?) and he somehow got nature magic, which was thought to be extinct.The seme has blond hair and is a prince from a neighbouring kingdom and the mc tried to make his sister fall in love with him but unintentionally her big bro, the seme fell in love.Ah and the mc has a big bro who has blue hair and a sister with red hair.
I read this on webtoon but can‘t find it anymore
