Christopher Bangchan and his group of athletes had just arrived in the school cafeteria when he noticed a girl, probably a new student, sitting in his seat

The boy smiled and sat down next to her, observing her sandwich

Bangchan: Do you know you're in my seat?

he asked, mocking her confused expression

Bangchan: You can stay, if you want but I want your sandwich

he pointed at the food

Bangchan: It's a fair trade, isn't it?
