I think you should re-read the series, just to get things straight. He didn't find out recently that him and Sera aren't related.
He found out she's not the ceo's daughter.
They were never related to begin with. His father and the ceo were best friends, then his father died and the ceo took him in as a way to show respect for his late best friend.
So, to summarize, they weren't raised as siblings and they do not share a single drop of blood.
Hope I wasn't too rude but it has been quite annoying seeing this type of comments every week
it’s really turning me away from the whole story…
