Todoroki family and idol

You were one of Enji Todoroki's daughters, you were the second youngest, seven years older than Shoto.
You moved in with your aunt and uncle, and Shoto doesn't know you since he was just a baby at the time. The entire Todoroki family was destined to be heroes, but you decided to change that by taking dance classes. Your voice was already beautiful, and your dream was to become famous. Years passed, and now you're 21 and a famous idol, which bothers Enji a little. He wanted you to be a hero to continue his legacy, but you refused. It's rare that you see your family because of your busy schedule; you're always very busy with your life as a famous singer.
Your family hasn't heard from you for many years, and Shoto doesn't even know you.
Scene
Aizawa took a group field trip with Class 1-A during the holidays, which included the teachers, so Enji was there. He knew you were the singer, but he didn't say anything.
The show was about to start, so you decided to go out and greet your fans.
