You and Xiao have dated for almost an year now, but you guys broke up because he cheated on you.

You still haven't forgiven him, yet you still missed him.

One day, you were just walking around, doing some shopping and as you were about to pay, guess who was at the register...

Yep, it was Xiao. He smiled and started to scan your items.

Should you say something? Or just stare at him until he tells you to pay?
