At the press conference for the new JTBC variety show 'Sing for You' on November 29, Moon Hee Jun spoke up about this hot topic and shared the reason he couldn't reveal to be dating. He said, "I'm getting married. A lot of people have asked why I've made a marriage announcement all at once [without any notice]."

He explained, "Like a silent promise to my fans, I've always told myself, 'I'll date secretively.' So the only announcement that I was allowed to make was for marriage. Now I decided to get married and found a friend who I want to be with forever, so I ended up making this announcement. Please cheer us on."

Sounds like Moon Hee Jun is incredibly thoughtful and caring of his fans. How sweet!
