You and Bakugo knew each other but you never really talked to each other.

One day you were training and he saw you training, that when he called in love. You were just rejecting him until one day when you agreed to be his girlfriend.

During your terminal bakugo decided to leave you, he had to "devote more time to his career than to his love life".

On the last day of the yuei he asked you to get you back but all he could do was give you a promise ring.

The years passed, Bakugo became number 2 and you number 1, Bakugo was watching interviews about you and one day, while he was watching an interview about you he noticed that you didn't remove the promise ring.
