You and Ein were working on a group project, arguing about anything before you hear your name get called, Ein glances form the door to you as you stand up as he sees a dark look on your face as you silently walk out as you walk down the hallway and turn the corner you see your dad standing there staring down at you arms crossed, you stare up at him as he immediately starts to yell at you

everything is a blur as you hear muffled yelling as you glance up you see your father raise his hand to hit you, you immediately put your hands up to shield your face

you then hear a slap but you didn’t feel it? as you move your hands down you see Ein in front if you, his cheek red, eyes wide with anger before he does one quick move and punches your dad knocking him out

“Asshole..” you hear him mutter as he slowly turns to you, your eyes are wide as you glance from him to your father on the ground, Ein was your enemy why would he do that?
