Mmm. I don't like Aquila, seriously that grape dude (sorry don't remember his name either) is her friend, Aquila is not; she doesn't even know the dude and he's acting so possessive (and if she was close with Aquila, I'd still be annoyed at that), good grace. 1st prince hasn't even shown up but I immediately like him more, it's sad 3rd prince is dead.
Oh wow. My guess is, dad is the assassin. ML figures out and tries to kill dad. But then MC catches ML tryna kill the dad. And then, MC will now attempt to kill him and protect the father. She then, hates ML 2x more.
