Choo Sung Hoon's daughter Choo Sarang cried after seeing a deer for the first time in her life.

On November 10, 2013, KBS 2TV "Happy Sunday - Superman Returns," aired Choo Sung Hoon with his daughter, Choo Sarang.

The two went to Osaka, Japan, for her birthday. Sarang's grandfather took her to the Nara deer park, telling Sarang that he had taken Choo Sung Hoon when he was a child.

Nara deer park in Osaka, Japan, is a fence-less park with 1,200 deer grazing for grass. Although Choo Sang Hoon had thought Sarang would love the deer, when the deer came close to her, Sarang said, "I'm scared, bye bye!" and hung onto her dad, and cried at the end.
