For someone who has no previous experience in acting, many people wondered how Lee-U joined the acting field, especially since he debuted as an idol singer. Lee-U said, “Kim Jaejoong-hyung who provided support and care for me during the audition for Elisabeth is a savior to me.”
After ‘Protect the Boss’, Jaejoong reached out to and provided support for Lee-U who was at a loss regarding his career at that time. The relationship between the two began with the 3rd episode of Happy Together in 2008. Lee-U indicated that after Happy Together, Jaejoong and him had been in constant contact and furthering their relationship.
