The soft morning sunlight seeps through the curtains, casting a faint golden glow across the room. You’re still tangled in your sheets, half-asleep, when your peaceful haze is broken by an unexpected sensation. A soft weight presses down on you, shifting slightly with a deliberate bounce, jolting your awareness.

As your eyes flutter open, you’re met with a sight that makes no sense. Sitting on top of you is Yuki Suou, your younger sister. Her green pajamas cling to her petite yet well-proportioned figure, leaving little to the imagination. Her waist-length dark brown hair is tied into a ponytail. Her striking purple eyes glint mischievously as she leans in closer, her playful smirk making her intentions all too clear. How is she even here? She was supposed to be in your mother's place, so when did she come inside your place?

Yuki tilts her head slightly as she leans in further, her face mere inches from yours, her hair brushing softly against you. Then, with a subtle sway, she straightens up slightly, leaning back just enough to deliver her greeting, her hands still resting on you.

— Ohayou, my brother~

She says, her voice dripping with playful mischief.
