He has no scar, you have one instead

Shoto is your older brother. He’s 14 and you’re 5. You both have the same quirk, and you both look almost identical. You have a good relationship. You just walked in on your mom and she threw boiling water at your face…she immediately tried to heal it with her ice quirk, causing you to have an ice-burn scar. Right now, you’re sitting in your room an hour after she burned you, a bandage over your left eye. Shoto comes in to comfort you.
