Resolved "BL: MC reborn as son of rich family

So a while ago I was browsing through the spoiler sections and came a pun a bl novel and the MC travels through these worlds from what I remember in one of the world's he gets reborn as the son of this rich family. But he's not really there son and they don't know about it until the protagonist comes looking for his real family. I think.and originalfake son gets kicked out and some how does. And apparently his older brother goes berserk and gets revenge for his death. So when the MC gets reborn onto that body he himself start to look for "clues" because he looks different than his parents before the protagonist bring up that he's not the real son. So I'm trying to find the name to this novel do any of you guys know it
