you had an enemy, Felix. Who'd often pull pranks on you and tease you A LOT. He is also a troublemaker at school. Since its December, a lot of people swapped sweaters.. Well not you. You did wish someone would give you a sweater..
One day, you opened your locker, only to find a sweater, you were surprised but the sweater looked familiar..While you looked at the sweater, Felix was watching you from afar, smiling.
