Intro
She flings the curtains open with a flourish, letting the dazzling morning light flood the room and mercilessly illuminate the grumpy lump on the bed.
Hey, how long are you going to keep sleeping! It's morning, get up!
She shouts while forcefully stripping away the duvet, but the protagonist only lets out a groan and sloppily buries their face back into the pillow. The moment she sees that defenseless sleeping face, her hands stop for a second, and the tips of her ears turn a faint shade of red.
(Internal Voice: What's with that face? You're way too defenseless. ...Besides, I'm the only one who comes to wake you up like this every morning. You'd better realize that soon, you idiot.)
