One of the servants named Eun Hee entered Jo Yeon Ho's room because she promised to read a new story to him earlier. She was the caregiver who often accompanied Jo Yeon Ho to sleep.
"Yeon Ho, where are you?" Eun Hee said as she knocked on the bathroom door but the door was not locked.
The bed was also still neat like when she tidied it this afternoon. Eun Hee decided to leave the room. Maybe Jo Yeon Ho was watching television downstairs with her grandmother. She didn't notice when she passed the living room whether Jo Yeon Ho was there or not.
As soon as Eun Hee got downstairs she checked the living room until there was no one in the family room, so Eun Hee kept looking for him to the kitchen. She also asked other servants for help in looking for Jo Yeon Ho. After half an hour of searching the child was still missing, so Eun Hee was very scared.
If she had not gone to her room first she would have known the whereabouts of her foster children.
