JTBC's 'Tokpawon 25 Hours' is composed of various segments such as experiencing jobs in Australia, a virtual trip to Auvergne, France, and a dessert showdown between Japan and the United States, with Red Velvet's Irene appearing as a guest.

This broadcast features Irene, who made her comeback with her first solo full-length album 'Biggest Fan' after 12 years since her debut. Irene captivated the studio with her unique visuals as soon as she appeared. The studio responded with comments like "She shines," and Lee Chan-won, who is from the same hometown, shared anecdotes about Irene's pre-debut days as a famous "ulzzang" in Daegu, saying, "If you ask seniors from Daegu, she was really famous in Chilgok."

A surprise support message for Irene was also prepared. The video letter featured a special guest personally invited by Jun Hyun-moo, who warmly advised the nervous Irene, saying, "It would be great if you show your true self," creating a heartwarming atmosphere. Curiosity about the identity of the surprise guest grew in the studio.

Meanwhile, the first video revealed the 'Jobs Like This in the World' Australia episode. The Australian Tokpawon experienced being a zookeeper, closely caring for and interacting with animals. They legally petted quokkas and fed snacks to capybaras, engaging with various animals. Also featured was the pygmy marmoset, a tiny monkey measuring only 12–16 cm in length and weighing just 100 g. Kim Sook expressed amazement, saying, "It looks like a doll you hang on a bag," and when the pygmy marmoset climbed onto the Tokpawon's shoulder, the studio responded with "So cute." It was reported that the Australian Tokpawon had high job satisfaction while experiencing privileges only a zookeeper can enjoy.

JTBC's 'Tokpawon 25 Hours' airs every Monday at 8:50 PM.
