Yoon Sang Hyun talked on the latest episode of "Ask Us Anything" about being jealous of his wife Maybee's close relationship with Ming Kyung Hoon!

On the September 5 episode of the JTBC variety show, Yoon Sang Hyun appeared as a guest with his "18 Again" co-stars Lee Do Hyun and Kim Ha Neul.

Early on the show, Super Junior's Kim Heechul mentioned that Yoon Sang Hyun had expressed some reservations about appearing on "Ask Us Anything" due to a particular cast member. And Yoon Sang Hyun jokingly declared that he almost didn't get married because of Min Kyung Hoon.

In the episode, Kang Ho Dong then asked Min Kyung Hyun if he knew Yoon Sang Hyun's wife; he said that they used to be labelmates at the same agency.

Yoon Sang Hyun elaborated that sometime in 2014, he had to go to Brazil for a shoot. He admitted that he had a small fight with Maybee before he left, adding that they were still not married during that time. Sang Hyun continued that he began to have second thoughts about whether he was going to marry her or not because of their fight. He was holding the idea when he went to Brazil and kept thinking of it for ten days while he was there.

When Yoon Sang Hyun returned, he went for a drink alone in the Cheongdam neighborhood, and the more he drank, a strong feeling came upon him to call Maybee, so he made a call at about 3 or 4 in the morning. But he heard a voice singing in the background and thought that it was a familiar voice.

Kang Dong Hyun then asked who was it and crack up by asking Ming Kyung Hoon to sing.

Yoon Sang Hyun shared that because he like Kyun Hoon and Buzz's song so much, he familiarized their voices. As he called Maybee, she told him that she went out with some men and women and the marketing team. Sang Hyun continued that he did not plan to see her after that call, but wanted to see who is with her. Yoon Sang Hyun ended up rushing off to see her because he was upset.

Yoon Sang Hyun clarified that he doesn't know that it was Kyung Hoon during that time. With a laugh, Min Kyung Hoon said, "So you came to beat me up?" Yoon Sang Hyun replied that he just wanted to see the guys whom Maybee was with because he heard a voice during their call, and she told him that they were drinking and singing at the karaoke bar.

Later on, the interview, Yoon Sang Hoon revealed that after he and Min Kyung Hoon appeared together on "Sam Bed Different Dreams 2- You Are My Destiny?" he realized that he doesn't need to worry about Kyung Hoon. He went to say that he regrets all the time he wasted worrying about him.
