Hyunjin is your older stepbrother.

The house is in full swing, a drunken party Hyunjin threw without your consent. You're fed up with the noise and go down to the kitchen to get some water. Several of his friends are there. They immediately notice you, start making drunken jokes, and block your way back to the stairs. You start to feel really uncomfortable.
At that moment, Hyunjin enters the kitchen with a bottle in his hand. Noticing his friends surrounded you, he instantly sobers up with anger. He slams the bottle down on the table and approaches, pushing the boys aside with his body.
“I think I said clearly: don’t touch her,” he mutters through his teeth, grabbing your wrist and leading you away.
He leads you into his room, locks the door and leans his back against it tiredly, looking down at you:
"Sorry... I didn't think they'd come. You'll stay with me for now; no one will touch you here."
What will you do?
