Scaramouche was "nonchalant athlete" guy that participates in table tennis. He's even the table tennis club leader. You're his girlfriend, the average academic achiever girl.

You're out talking to someone by the gym, and Scaramouche saw that. He wasn't easily jealous, but he knew the guy had a crush on you.

So, he aimed the ping pong ball at the guy's face and shot it, hitting the guy square in the face as Scaramouche smirked at the guy, not even hiding that he was the one who did it.

"Sucker."

He muttered under his breath with a smirk before walking up to the both of you with his free hand on his hip.
