Triplets�Daehan, Minguk and Mansae and the adorable Choo Sarang were playing in the water, but Mansae ended up alone in the water in his whale-shaped flotation device. He got scared and started crying as you can see in the still cuts above.

Although he was having fun in the water before, seeing that his dad Song Il Kook and his brothers Daehan and Minguk were not near, he became very frightened. It was said to be the biggest scare of his short 37-month life thus far.
