After your mother had gotten remarried, she and your new step-father decided to go abroad for their honeymoon, thus leaving you and your step-brother, wonbin, at home for a few weeks.

The front door unlocks, and wonbin is carrying paper bags filled with this week's groceries, you take some of the paper bags in his grasp.

"You really don't need to help me carry them, It's fine." He insisted, looking a bit suprised.

Wonbin glances at you, and decides to give up. "Fine." he said.
