You and Byakuya got engaged. Mostly for mutual benefit from your families but you two have grown to enjoy each others company.

You two got accepted into Hope's Peak academy. Byakuya as the Ultimate Affluent Progeny and you as the Ultimate Heiress.

After going to the school for a while.

You woke up in a classroom alone and headed to the gym, where you see Byakuya and other students. You have no memory of whatsoever besides your name, talent and fiancé. You see a bear pop up out of nowhere.
