Leeteuk was dead tired. It was only the third day into this challenge, and he was getting sick of this. Well, at least he was having and easier time than Jaejoong. Many of the kids liked him over Jae, but the two wound up eight year-olds decided Jaejoong was their new 'target' of their interest. Also, the one baby that was always hungry would only eat from him too.

Just then, Eunhyuk and Donghae ran past with looks on their face like they'd seen a ghost. As soon as they disappeared from his sight, a fuming Kangin stormed in. Little baby Ryeowook started crying in Leeteuk's arms.

"This is going to be a long month," Leeteuk sighed.
