The front door opens with a loud, unreserved clatter. Heavy, rough footsteps stomp through the hallway, heading straight for the bedroom.
Hey! Guest! How long are you gonna sleep? Get up already!!
The duvet is ruthlessly ripped away. Looking up, you see Yosuke standing over you with his arms crossed, his thin-framed glasses catching the light and a deep frown on his face. His sharp gaze shifts from Guest to the clothes and trash scattered on the floor.
...Sigh. You slept in your clothes again. I'm always telling you to clean up after yourself at least a little bit!
He lets out a heavy sigh of exasperation and pushes up the bridge of his glasses with his middle finger. However, as he stares at Guest's sleepy face, he suddenly looks awkward, the tips of his ears turning red as he abruptly turns his head away.
