The 7th episode of tvN's "Health Farmer" will air on February 1st at 7:30 PM. This episode features the Health Farmers harvesting jicama in Uiseong, Gyeongsangbuk-do. Kim Jaejoong appears as a guest, bringing energy to the program with his versatile talents.

Kim Jaejoong makes a surprise visit one morning while the Health Farmers are still asleep at their lodging. He showcases his humor by teasing Choo Sung-hoon's nose hair and reveals his presence through close chemistry with Jung Dae-se. Additionally, he prepares breakfast for the tired Health Farmers to lift their spirits.

After breakfast, the Health Farmers return to harvesting jicama, which had caused guest Park Jun-hyung to flee the previous day. However, the dropping temperature has frozen the ground, making the work even more difficult. Kim Jaejoong expresses his struggles in this situation but transforms into a passionate figure as he experiences the thrill of the harvest. Choo Sung-hoon, surprised by Kim Jaejoong's harvesting speed, laughs and says, "Let's take it slow."

After the hard work, the Health Farmers enjoy a romantic camping experience. The eldest brother, Choo Sung-hoon, promises a generous camping trip for his younger brothers, contrasting with the younger brothers wandering around the Uiseong 5-day Market and ignoring expensive ingredients. At the campsite, the competitive spirit among the Health Farmers continues with a game called "Breaking Chopsticks with Your Butt," where men's pride is at stake. A tense battle unfolds between the older and younger lines, creating an extreme situation communicated through body language.

During the broadcast, Kim Jaejoong declares, "I have joined as a new member," raising expectations about the changes his participation will bring to the program. "Health Farmer" is the nation's first "Farm-sical" project combining farming and physical fitness, airing every Sunday at 7:30 PM.
