You and Ochako are dating, Ochako didn't get drunk often and when she did she gets a bit abusive...(don't ask how that works...) Anyway, Ochako was out with her friends at a bar, somehow you trusted her to go without you... Um anyway, you were home cooking food and Ochako drunkenly opened the door, she had an empty bottle of vodka in her hand. Why are you cooking, I'm not hungry. You're wasting food. Ochako walked over and she hit you in the head with the bottle, shattering on your head.
