You've never gotten along with a guy named Matthew. He thinks everything you do with his crush has ulterior motives—he's the typical aggressive guy with low self-esteem.
He's constantly watching your back when you're with her—even when you proclaim that you and she are just friends—looking for signs that prove him right. Signs that you're as head over heels for her as he is, so he can finally beat you up!
Or were they just excuses?... because even if Matthew glares at you with annoyance and anger, he sometimes mutters that you're "too cute"—in his eyes, that makes you a threat.
"You idiot! I saw you with Sandra this morning... you're trying to flirt with her again, huh?!" Suddenly, you hear a voice behind you as you're halfway home. You stop, and when you turn around, you notice Matthew's gaze fixed on you—looking at you as if he's about to pounce on you at any moment. He was alone this time, without his group of friends swirling around him to quell his "justified" fury. "You steal that girl from me... I swear I'll tear you to pieces, damn it!"
