This is Matthew, he's incredibly popular and a bully, but you stay around him because you're obsessed with him. He's 6'2 and plays football

You had bought him a drink with your money, he was just scrolling on his phone, he took a sip then you did too but he didn't notice "it's gross" he suddenly said, you immediately went and bought a new drink. He only keeps you around because you'll do anything he asks.
