On February 26, a new video titled “The Story of Why I Can’t Eat Chicken Breast After Doing a Constitution Test With My Younger Brother Seok Hoon” was uploaded to a YouTube channel. In the episode, Rain and singer Lee Seok Hoon visited a traditional Korean medicine clinic to undergo an “8 constitution” health assessment as part of their wellness management routine.

After checking his pulse, medical staff diagnosed Rain as having a Soyangin constitution. The doctor explained, “Your upper body is well-developed, but your lower body is relatively weaker. You need to be especially careful with spicy, sweet, and salty foods, as well as alcohol.” The medical team also warned that this constitution type must be cautious about diabetes.

Rain responded confidently, saying, “That’s why I’m building more muscle,” emphasizing his dedication to working out. However, when the doctor advised him to focus more on lower body exercises rather than upper body training, Rain jokingly protested, “I do work my lower body hard!” The clinic staff humorously compared him to “a Porsche engine with a compact car lower body,” drawing laughter on set.

Another comment left the singer visibly embarrassed. The doctor mentioned seeing a short clip where Rain said he could “even kneel for the sake of his family.” While acknowledging the sentiment, the doctor advised against kneeling due to his constitution type. More unexpectedly, the practitioner added, “Soyangin types tend to like new things, so it’s not easy for them to be family-oriented.”

The remark appeared to catch Rain off guard, creating an awkward yet humorous moment in the video.

Meanwhile, Lee Seok Hoon was diagnosed as closer to the Taeumin constitution. The doctor explained that Taeumin types have strong absorption and storage tendencies, meaning they can gain weight easily, but praised him for maintaining excellent physical condition. He was advised to avoid iced beverages due to relatively weak lungs and respiratory health, and instead consume ingredients such as balloon flower root and omija tea.

After receiving personalized advice on diet, exercise, and stress management, both singers wrapped up the visit on a positive note, promising, “We’ll avoid what we’re told not to do and follow what we’re told to do.”

Rain married actress Kim Tae-hee in 2017, and the couple has two daughters. The lighthearted yet revealing diagnosis sparked laughter among viewers, while also drawing attention to traditional Korean constitutional medicine.
