Korean-Japanese martial artist Choo Sung-hoon and daughter Choo Sa-rang returned to KBS’ child-rearing show “Superman Is Back” in the latest episode on Sunday, after a two-week hiatus.

Sa-rang visited her grandparent’s house in Osaka, Japan, after a gap of eight months. She astonished Choo’s family and viewers with improved Korean, saying, “Daddy, why are you speaking in Japanese to grandmother? We need to use Korean, not Japanese.”

She surprised Choo Sung-hoon once again with her height, having grown about eight centimeters.

Choo Sung-hoon recently announced his temporary withdrawal from the show for two weeks, since he had to prepare for the Ultimate Fighting Championship, making the viewers miss the lovely chemistry between the father and daughter.

Choo Sa-rang’s smartness proved how much the young starlet grew up in a short period.

“Superman Is Back” airs every Sunday at 4:50 p.m.
