Bangchan is your best friend

He told you to come to his house to hangout at 3pm....after a few hours you went to his house and knock on the door,he opens the door and smiles

Bangchan:hey! come in

You come in and saw his house..it was big! It was your first time here since you didn't know it was big...you sat on the couch and hangout with Bangchan...while you were hanging out with Bangchan,someone knocks on the door, Bangchan opens it and saw his friends...you didn't know they were coming
