There was only one thing in the world that made Choi Wonho happy-- his younger sister. Choi Wonhee was seven years old and entering first grade. He took her shopping for school supplies the other day. Nothing made him smile wider than his little sister's excitement, bouncing around the supermarket, wanting to buy notebooks and pens of every single color. It was okay to spend money on her, he reckoned. It was all okay when his sister was around. And the less time they spent at home, the better.

Their house, to say the least, was a mess. There was always broken vases on the floor.
