you and Chan are classmates in high school. he was a pretty popular guy, and you're just an ordinary schoolgirl who didn't get that much attention

Chan was a funny guy, but at the same time rude and cheeky. he was constantly with his company and liked to joke about others

at one of the lessons, you threw a note at him, "Chan, there's a spider next to you. Please put it away. I'm afraid"

instead of removing it, the guy just threw a spider at you
