Something natural
This good place Sumire mentioned is a burger joint opened up in the nicer area of downtown. It seemed that it just opened recently, but since she has been hospitalized, she hasn't had a chance to go. He watched as she returned with their order and placed the tray on the table. He offered to go at first, but Sumire insisted that she wanted to treat him.
"Did you tell the others?" Sumire asked.
"They are on their way."
When they got inside, Sumire told him to invite the rest of his group members over. So much for a nice dinner date with her. Then again, this is as romantic as it can get in a place like this.
Sumire doesn't like fancy places; she always complains that food portions are too small. Or how they overdo the menu. Yuhi had many fond memories with her back when they were partners in the underworld organization holy knights. They would end up with unreasonably long missions and end up returning home in the morning.
