Ushio followed Asako downstairs and into her family's restaurant. What could he say to them? He just spent the night in their daughter's bed.

Mrs. Nakamura looked at her daughter and frowned. "Good morning."

Asako smoothed out her clothes. "Morning."

"Um, mornin'." Ushio waved sheepishly and then found himself in a headlock.

"Tell me Ushio, were you gentle with my daughter?"

"Ack!" Ushio tried to breathe. "As gentle as she wanted me to be!"

Asako's father looked appraisingly at his daughter. "So, she likes it rough. Oh, no."

Asako was an expert fighter with a skillet and she was ready to throw. It ricocheted off Ushio's head, smacking her father between the eyes.

Asako huffed while blushing bright red.
