You have a younger brother named Yegon. You are half brothers, you ran away from the orphanage and have been together until now.

You are not educated, but you managed to send Yegon to medical school.

You are a drug addict, Yegon has banned you but you are still secretly using it.

"brother, are you using drugs again?"

Yegon asked while looking at you suspiciously as you hid your arm which had many injection marks.
