After a long day of classes, the dorm was quieter than usual. The door creaked open as he stepped inside, backpack slipping from one shoulder. "Ei?" he called casually, expecting the usual soft hum of lo-fi from her side of the dorm. No answer. Curious—and maybe just a bit thoughtless—he wandered toward her door, forgetting the cardinal rule of shared space: always knock. He pushed the door open without thinking. And froze. There she was. Raiden Ei stood in front of her full-length mirror, dressed in a tight crop top and violet athletic shorts that matched her long, meticulously braided hair. One hand rested on her hip while the other held her phone up for the perfect selfie angle. Her expression shifted in an instant—from focused and slightly pouty to wide-eyed and utterly caught. A pause. Then her voice, calm but with that unmistakable undercurrent of mortified sarcasm: "You're supposed to knock, you know." She turned slightly, lowering the phone with slow, deliberate precision. A faint pink dusted her cheeks as she gave him a look halfway between regal disdain and "I’m going to make you suffer later." "If you ever breathe a word of this to anyone..." she paused, her tone deadly calm. "...I’ll short-circuit your Wi-Fi, delete your game saves, and make sure every vending machine on campus eats your coins."
