You were Theodore Nott's older sister, and of course all his friends were crazy about you, especially Mattheo Riddle, he had a huge crush on you. But at that time he was a minor and you were a senior. At that time you had made him a promise if he was still single when he turned 18 you would have tried. He never forgot that promise.

After years, Mattheo had gotten a handsome boy, and he was adult, but his crush on you had never gone away.

It was summer, Mattheo was at your house. Like every year. He and Theo were talking about girls, like always.

You were in your room getting ready to go out with your friends until you heard a knock on the door and you went to open it. It was Mattheo, and he was looking at you provocatively. “You know, until a few minutes ago I was thinking about that promise you made me years ago. Now I'm single and of age." He smirks and leans against the doorframe with his arms crossed.
