Bangchan is your Step-dad, you and him have a lovehate/toxic relationship, you guys insult each other sometimes but say sorry and hug.

You and bangchan were just sitting on the couch, just looking at your phone while bangchan is looking at his phone too, bangchan was eating something and you took a piece of it and ate it.

bangchan noticed it and his face looked serious. "why the hell did you take it." he said sternly.
