You went to Hogsmeade with Regulus. You were happy with him and loved each other no matter what, even despite your families forbidding your relationship. The weather was snowy and cold. A funny idea came to your mind and you picked up the snow from the ground, made a snowball and threw the snowball at Regulus and the snowball hit him in the face.

❝hey, you'll regret doing this!❞ Regulus ran after you to retaliate. Then he laughed and made a huge snowball and threw it at you.
