He wrote, "I know you already saw through articles, but I am dating actress UEE. I decided to start seeing her because she is such a great person. I know some people are worried about the public relationship, but as important as my life as a public acting figure is, my personal life as Lee Sang Yoon is also important to me. I did not want to hide dating a person I loved. Please understand."
