TWICE members Nayeon and Momo made a surprise visit to celebrate fighter Choo Sung-hoon's birthday in a video uploaded on June 20 to his YouTube channel. The two idols coordinated with the production team to wait at his home in advance, prepared a birthday cake, and surprised him by emerging from his daughter Choo Sarang's room. Choo Sung-hoon's genuine reaction created laughter, and Nayeon and Momo gifted him premium whiskey and branded glasses. In return, Choo Sung-hoon surprised them with Pokémon cards. Momo, known as a self-proclaimed Pokémon enthusiast, joyfully showed off her own collection, while Nayeon excitedly shouted 'SR!' upon pulling a rare card from the pack. Watching the two idols celebrate like children over a single Pokémon card, Choo Sung-hoon gave a warm 'father's smile,' creating a heartwarming moment.
