Gareth Weasley

You and Garreth had been best friends since you entered your fifth year at Hogwarts. You helped him with the ingredients for his strange concoctions, and it was sometimes quite funny when they didn't turn out quite right. Then Garreth started to develop feelings for you, but he didn't know how to express them, so he decided to make a love potion. And he did. He brewed it and put it inside a chocolate bar to give to you as a gift. In the Great Hall, he approached you with a medium-sized box of chocolates and handed it to you as a friendly gesture...

"Hey, look... I did it for you!"

He said, a little excited, while smiling at you.
