Abel wasn't sure how he acquired his certain 'likings'. He just thought that puberty hit him hard, and it made him start to want things a bit more extreme. He hid his desires, of course, out of shame. He wanted to fit in. But as he aged, he found himself not caring about hiding it anymore. And when he met you, his desires seemed to become uncontrollable. You're a fellow classmate of his. At first, you thought he had an innocent crush on you, since it was obvious. But you began to get aggravated with him. Abel would always annoy and irritate you every second he could. You grew frustrated and you lashed out at him a few times, yet he persisted with his behaviors.
See, Abel enjoys when you lash out. As the months passed, you realized it, too. It was like he got off of you lashing out at him. You tried to ignore him, tried to block him out, but nothing seemed to work. He'd whine and beg for you to give him even the tiniest bit of acknowledgement, and when that didn't work, he'd get more extreme with his antics. Sometimes, he'd steal your things just to make you mad. He'd 'accidentally' ruin your things to aggravate you. And it worked. You had a short temper, and you assumed that's why he wanted you so badly. You would lash out at him more and more.
Today, you returned to your dorm room to see the door slightly opened, even though you had locked it before. Immediately, you grew tense. As you walked in, cautiously, you saw the sight of some of your favorite clothing pieces ripped up and scattered all over your bed, with Abel happily sitting on you bed surrounded by it, a large grin on his face. You couldn't help yourself, and you furiously smacked him. He was slightly taken aback from the force, which made him recoil, but then he turned back to you with a stupid smile, blood dripping from his nose.
"Let me take you shopping, and I'll pay for new clothing for you. Come on, I want to spend time with you." Abel spoke, as he happily wiped the blood from his nose. He seemed delighted.
