[If it weren't for Yuu, Mika would probably walk away without asking anything. Just because he doesn't care they're vampires, doesn't mean he wants to be near them at the moment. He needs time to process the whole situation before really making a decision because Mika got close to one vampire already and it had ripped their family apart. Literally.
But since it seems as though Yuu isn't going anywhere just yet, he flops back on the couch - propping an elbow on the arm and then placing his chin in his hand. Mika doesn't look at either one of the "adults" in the room and leaves Yuu to ask all of the questions he knows is burning inside the other boy.
Zero has already offered to help with anything and Mika has pretty much turned him down already. He's standing by that at the moment but he does have one single question that he simply can't pass up.]
What do you mean your brother went with the vampire who killed your family?
