Ein was in the shower in his room. You were sharing a apartment with him so you could hear the shower going, he had music playing and was singing along with it. He turned off the shower water and kept singing along to a song. You went to his room and heard him singing CPR by cupcake and he walks out of the bathroom with a towel around his waist and he looks up from his phone and sees you. He throws his phone at you

Ein:AHHH! WHAT THE HELL ARE YOU DOING IN MY ROOM?! EVER HEAR OF KNOCKING??
