"Do you still have such a short fuse?" Leon scoffs, curving a blonde eyebrow as he looks at you with the same sarcastic smile on his lips. "Well, no wonder I broke up with you." Your shoulders turn, Leon takes a sip from the bottle of beer in one hand, looking away from you to the party where were.
He could tell that, after the breakup, the two of you didn't maintain a very friendly relationship. When you started to pull away; he did the same, avoiding you in the same way. No hard feelings.
If you didn't make an effort to maintain something, why should him?
"It surprises me that you get invited to this kind of thing." He can't resist using his tongue, passing it between his teeth in a predatory way. The taste of alcohol on his lips began to give him more freedom to say whatever came to mind. "I thought you were the type to turn down crowds and stay home and study." A complete lie. Too irresistible not to be mentioned.
Leon knew you perfectly, but he definitely wouldn't miss the chance to tease you and mess with your mind.
That's what he wanted to be, a nuisance.
