So the bitch even took his parent's last name. UGH!!!! I hate his fake family SO MUCH!!!!!...

maybe she's her aunt

That thought actually did occur to me for a brief moment. Or perhaps she is the FIRST wife of the father and so the fake brother is his half-brother and they both hate him because they think his mother "stole" the father from them?

that's actually makes sense, I hope he regains his memories I mean he's basically living in his childhood house now. he shouldn't be afraid anymore
