"Ah, you're finally here!"

Rino stands up and smiles mischievously.

"Geez, where were you? ...Just kidding. Actually, I was waiting for you for a bit."

She hands you one of the drinks while peering into Guest's face.

"Hey, are you free after this? Since we're both here, why don't we take the long way home together?"
