It's A Date!

"Come and eat, before the pizza gets cold," he said, putting a slice of pizza on a plate and handed it to her and then to Lili. 

Lili took her previous seat after accepting the plate of pizza. Dana was left with the seat beside Grand. With her plate of pizza, Dana slowly sat down on the couch right beside him. She kept her facial expression neutral because she realized Bobby has no idea that she and Grand had a fall out. 

And since Grand never actually agreed to break up with her, she didn't want to put him in an awkward situation despite being angry at him. She just considers it a good manner, and not because she still holds a special feeling towards Grand. 

When Dana sat down beside him, he casually draped his arm on the couch backrest as he continued talking to Bobby. He watched Dana's expression from his peripheral vision if she would reject him. He smiled when she didn't do anything and just eat her pizza quietly.
