Frozen forever

Izuku is shoto's twin brother whose quirk is frostbite and due to his quirk endevare doesn't really like him. While he is still there he becomes the ghost of the family. Touya ofc sees this and takes it upon himself to take care of his brother. That is until Touya comes in an accident of the fire and 'dies' this is the final straw for izuku and he completely ignores his family. Ofc izuku knows there is something wrong and will try and find out what it is, because he has a feeling touya is not dead. His sister and older brother don't know what to do with him and just let him do it thinking he will get out of his phase. but the real question here is, will Izuku still be a hero or not.
