On KBS 2TV's "The Return of Superman," the friendly moments between Guillaume's daughter Leah and her boyfriend Hoyun will be revealed.

First aired in 2013, "The Return of Superman" (directed by Kim Young-min, hereafter "Sudol") has consistently received viewers' love for 13 years. The program was selected as the most influential observation variety show at the "2026 Brand Customer Loyalty Awards," establishing itself as the nation's childcare variety program.

In the recently aired episode 636, Guillaume and his daughter Leah invited special guest Hoyun to their villa in Yangpyeong. Hoyun appeared wearing a bow tie, showing off an adorable look. As soon as Leah saw Hoyun, she held his hand tightly and gave him a tour of the villa. The two showed their closeness by holding hands in the ball pit and jumping together.

During mealtime, they fed each other food and continued their pretend play. In the process, Leah directly expressed her feelings, saying, "I like Hoyun the best." Surprised by this, Guillaume showed his jealousy, saying, "Leah, come to Daddy's side."

In this episode, the sweet friendship between Leah and Hoyun, as well as Guillaume's reaction, is expected to bring new fun to viewers. KBS 2TV's "The Return of Superman" airs every Wednesday at 8:30 p.m.
