'THE Delicious Guys' featured singer Hanhae as a surprise guest.

On the broadcast of 'THE Delicious Guys' on the 16th, they visited a school snack bar and a grilled meat restaurant for a special segment recalling the past.

The first restaurant they visited was a snack bar that reminded them of flavors from their school days. Moon Se-yoon brought along cassettes and old songs to stimulate memories as a taste tip, reviving the 90s vibe. Just as they were getting lost in nostalgia, a mysterious live audio was played by the production team, catching the members off guard... The identity of the audio was revealed to be a live stage by singer Hanhae.

Hanhae surprised the members by performing Lee Moon-sae's 'In the Rain' as a human taste tip. Moon Se-yoon, who was a close friend, was also left speechless by something he didn't know. The members cheered on as he and Brown Eyed's 'It's Already a Year' showcased an impromptu duet, receiving loud applause. He noted, "I appeared to fulfill Moon Se-yoon's taste tip request to bring in a good singer to perform live" and shared the pleasant news that the song 'It's Already a Year' entered the TOP 100 for the first time in four years.

In response, Kim Jun-hyun said, "The era of the Kim Seong duo has come. The curtain was raised by Moon Se-yoon and Hanhae," extending his congratulations.

Hanhae, who appeared as a human taste tip on 'THE Delicious Guys,' enjoyed the eating show with the members, showcasing his entertainment skills without reservation.

Hanhae remarked, "I really love food. I recently hit 90 kg. I've gained over 17 kg," shocking everyone with his weight gain confession and bringing excitement to the scene.

Despite needing to leave for his existing schedule, Hanhae maintained focus on the food until the end, even making a 'New-Dung' move of taking out cold noodles, impressing 'Original Dung' Kim Jun-hyun.

After finishing his schedule, Hanhae continued the eating show at the second delicious spot, a grilled meat house. His sincerity toward food and explosive sense of humor made everyone burst into laughter. He also showcased a delicious chemistry with the members, hinting at expectations for adding more members.

'THE Delicious Guys' airs every Friday evening at 8 p.m. on Comedy TV.
