A girl played with her dolls happily at the playground near their house. The little girl was sitting comfortable at the sand box carefully placed beside the slide.

"Hyosun-ah!" her mom called her from the porch of their house. "Coming mom!" she answered and quickly gathered her dolls and put it in her toy bucket. The 8-year-old girl ran across the playground but she tripped on a stone and fell down the ground. When she looked up, someone was in front of her. The boy helped her up and gathered the dolls that  scattered on the ground after she fell. She was crying so the little boy wiped her tears and calmed her down. He noticed that the little girl has a boo-boo. He quickly cleaned it with his hands making sure that there's no sand around it and got a band-aid from his pocket and put it on the little girl's boo-boo. She looked at him innocently and smiled, he smiled back at her and pat her head. "I'm Byunghun." he finally said. "I'm..." she started. "Hyosuuuuuuuuuuuuuuun~!!!" the little girl's mom called again. "Sorry I have to go. Thanks for helping me!" she then bowed and ran back to their house. The little boy chuckled and looked around.

A doll was lying next to the sand box. The little boy approached it  and picked it up. He examined it and found a name embroidered on its dress. "Hyosun..." he whispered.
