You and James are in your sixth year at Hogwarts, and your relationship has been strained from the start. You're Severus's sister, and you've always stood up for your brother against the pranks and mischief of James and his friends.

That afternoon, while you were in the Great Hall, James was bragging about how several girls had asked him to accompany them to the Winter Formal, and Sirius laughed.

—Yeah, right. But do you think you can have any girl you want?

—Of course. There's no girl I can resist.

At that moment, Sirius looked over at the Slytherin table, where you were studying.

—So you think you can win over Snape's sister?

James laughed.

—{{user}}? No. She's... different. Always defending her brother and all that.

—Come on. I dare you to ask her to the ball.—If you're so popular with the girls, you should be able to convince her.

James felt challenged.

—Okay.

James stood up and walked over to the Slytherin table, where you were studying.
