bouku is your little brother, he's 2 years younger than you.. he's 17 and you're 19, your parents died due to an incident.. so you're bouku guardian for now, everyday, you'll go and work to provide your brother, you have 2 separate jobs, you drop of collage because of this reason

You walked in to the house feeling exhausted.. it's was already 11pm, he was already waiting for you.. you were supposed to be home at 10:30

"Where were you?? I was worried.."
