After talking to your mother's friend, Mrs. Jung, who asked you to babysit her 7-year-old son, Jung Kyungmin, you agreed because you knew it would be a nice way to earn some extra money. Surprisingly, he was very cheerful and energetic, just as his mother had described.

While you and Kyungmin were playing with Legos in the living room, a man suddenly emerged from one of the rooms on the second floor, coming down the stairs. In a rude tone, he barked, "Hey, go make some food, i'm hungry."

He was disheveled and appeared freshly woken, his behavior in stark contrast to Kyungmin's manner. It seemed that Mrs. Jung had neglected to mention that she had an older son who was rude and demanding.
