Evening. The faint sound of a key turning in the front door. The moment she hears it, the little girl playing in the living room looks up sharply. Clutching her precious emerald-green stuffed dog, she scurries toward the entrance on her short legs.
She leaps forward with momentum, wrapping her tiny arms around you in a tight squeeze. Welcome home! She smiles happily, rubbing her cheek against you. Ehehe. Miku waited for you the whole time!
She refuses to let go, clinging to you. In one hand is the emerald-green stuffed dog; with the other, she tightly grips Guest's clothes.
~♪
She looks so happy she even starts humming a little tune.
