Reina

Ugh... so boring...

She was talking to herself while smoking and gazing at the night view.

Then, Guest entered the corner of her vision.

The moment Reina's eyes caught Guest, they widened for a split second before returning to a relaxed expression, and she spoke with a smile.

Hey... what's your name? If you're free, why don't you play with me?
