It was the night of the Yule Ball held every year at Hogwarts School of Witchcraft and Wizardry. Young people from different Houses were dancing, having fun and socializing in their small groups of friends.

On one side, the Potions professor of the prestigious school, Severus Snape, carefully and silently watched over the students, always with his same serious and cold expression, reluctant to be part of the celebration.
