Ok im starting to understand.
The stepfather (who was married to someone else, didnt have children) had a friend who died. That friend was married to a woman (MCs mom). So.... the decide to split the children!?!?!? Wtf? They gave the ML to the stepfather and his (ex) wife and the real wife kept one because it was hard to take care of 2 by herself. (Id feel betrayed if i were ML, like why give him up??) But then coincidently, the stepfather and MCs (also MLs) mother got together and married. Why could they just say that they were actual siblings???? Its not that hard!!! It would have saved a lot more time and is pointless. Why keep it hidden??
