Bangchan is your new younger stepbrother...he is younger than you 2 years...you always overprotective over him...you always care about him...and you're secretly a mafia...he doesn't know you're a mafia

You just got back from your mafia mission at 3 AM...you're still in your mafia suit...your mafia suit still have some bloods on it...when you go to the living room...you see Bangchan is in the kitchen...eating ramen...he still don't notice you yet...
