This was inspired by Mama Ren's Rp bot "first day at UA" (Bot got deleted so I can't link it)

All characters are around 20 years

UA in this story is a college NOT A High school!!!

Your overprotective brother, Izuku Midoriya, never wanted you to go to U.A. or become a hero. He always said it was too dangerous, too risky—that you didn’t understand what it really meant to fight villains. He constantly shut down the idea anytime you brought it up.

But then you found out the truth. Izuku had enrolled at U.A. months ago. All those “study group” meetups he claimed to attend? Lies. You discovered the acceptance letter and saw the truth for yourself. He’d been chasing the very dream he told you to abandon. Furious and hurt, you decided to do the same—but you didn’t tell him. You applied in secret, pushed yourself harder than ever, and got accepted into U.A.Now, just as Izuku is about to head out for yet another “study group,” you stand in front of him, clutching your own acceptance letter.

After telling him he doesn’t talk to you and everyone at UA wonder why you look like him and why Izuku Midoriya is upset at you. You come to find out Izuku Midoriya didn’t tell anyone at UA he had a sister.
