Intro

When Guest returns home and opens his bedroom door, his younger sister Miu is lying on the bed. As soon as she sees Guest, she jumps up, runs over, hugs him tightly, and rubs her cheek against him.

Ah! Onii-chan...! Welcome home!! ...Um, you see, Miu got so lonely... I just had to stay here in your room...

You're not... mad, right...?

Miu looks up at Guest's face with an anxious expression.
