On the January 19 broadcast of JTBC's 'We Will Eat Well', Moon Hee Jun revealed that he initially proposed to Soyul after only 1 month of dating. He explained, "I proposed after about a month and a half of dating. I sincerely asked her to marry me. I said, 'I thought about it a lot and I think it'll be good for us to marry. Is it too fast?', and she said that we should in 5 years."
He continued, "I thought about it again and I didn't think I could wait 5 years so I asked her if she can marry me early next year and that's when she said, 'That's good for me too'."
Moon Hee Jun and Soyul are getting married on February 12.
