Recently Sang 'Da S is My Sister-in-law' – Relationship Between Rain and Koo Jun-yup Exposed

42-year-old Asian superstar Rain (Jung Ji-hoon) recently performed at the Kaohsiung Music Center, mentioning that he respects senior Koo Jun-yup, who was heartbroken over the sudden passing of Da S. "The one who passed away is my sister-in-law, although I have never met her," he led the entire audience in a 10-second moment of silence for Da S, which was moving. According to exclusive news from "Apple News", the reason behind this is because Rain and Koo Jun-yup have a sworn brotherhood, and they are quite close in private.

Koo Jun-yup now has a good friend from Korea named Michael, who has been in Taiwan for a while, accompanying him through this difficult time. It is understood that Michael, Koo Jun-yup, and Rain have a sworn brotherhood, with Michael being the eldest, Koo Jun-yup the second, and Rain the third; they have private connections and deep ties. Michael has a significant business presence in New York and Korea; he left his business unattended to specifically fly to Taiwan to accompany Koo Jun-yup.

Rain, during the concert, after performing his hit song "Rainism", suddenly put on a sequined shirt, explaining that it's not out of modesty, but with a serious expression he said, "There is a reason I put on the shirt. In the end, I really want to talk about my dear senior Jun-yup, it’s very regretful.” He expressed heartbreak over Koo Jun-yup's sorrow from losing his wife. 

Rain, putting aside his smile, sorrowfully said, "Our Jun-yup is a senior respected by all K-POP artists in Korea, it is very sad, we all feel very regretful. Actually, the person who passed away is my sister-in-law, although I haven't met her, since I'm here as a junior, I feel that a moment of silence is the best choice for her. For both of them, can we have a 10-second silence?" He then closed his eyes and bowed his head, leading the audience in mourning. 

Celebrating 26 years in the industry, Rain’s achievements in the K-POP circle are well recognized, and senior Koo Jun-yup's status, having started with the legendary group "Clon" for 35 years, is even more esteemed. Rain further stated, "Just as I said before, he is a senior I deeply respect. As I just mentioned, being here as a junior, even if we cannot meet face-to-face, I think praying from afar is what I should do, and please everyone pray and support Jun-yup. He is the greatest senior I know, the most upright and kind person. Thank you, everyone, thank you."
