Actor Shares Story of Winning Over K-Pop Idol Wife Who Is a Decade Younger

Girl’s Day Minah’s husband, actor On Ju Wan, shocked fans by revealing they dated openly for five years — with zero media coverage.

The confession came on the April 10, 2026, episode of MBN’s Moo No Plan Season 3, where On Ju Wan joined hosts Jun Hyun Moo and Kwak Tube for a food trip. When asked if the couple kept their relationship hidden, On Ju Wan said,

“Not really. We walked around holding hands,”

and added,

“For whatever reason, there were no articles about us at all. We were openly affectionate.”

Jun Hyun Moo joked about dating rumors and On Ju Wan laughed it off, revealing,

“Minah and I actually talked about that once… We figured maybe the world just isn’t that interested in us.”

The couple met on the 2016 K-Drama Beautiful Gong Shim despite a 10-year age gap that raised some eyebrows. On Ju Wan said his move came during a musical they did together.

“As time passed, I started doing musicals, and Minah said she wanted to try musicals too. She auditioned and joined. I played a role in protecting her, and since we practiced up to 10 hours a day, I ended up spending a lot of time with her and doing stuff for her.”

On Ju Wan was the first to confess.

“I was the one who confessed first, in the practice room. While everyone else was rehearsing, I told her, ‘Minah-ya, I think I like you.’”

They tied the knot, but their low-profile relationship and lack of media buzz continues to surprise.
