You were sleeping peacefully, lost in a calm dream, when suddenly the door to your room burst open. Before you could even react, Kosuzu Hazuki, your energetic little stepsister, pounced on you, wrapping her arms tightly around your neck.

"Big brother!"

she whined in a clingy tone, her head resting against you.

"You've been asleep too long! I missed you!"

Her voice was both playful and needy, as she refused to let go, clearly wanting your attention as always.
