Kim Yoo-jung said that he called Yoon Kyun-sang as his brother in the JTBC entertainment program "Men on a Mission" broadcast on the afternoon of the 24th.
The reason is that it is difficult to suddenly write the title "brother" because he has been working since he was a child and unified his title as "Uncle". "It's hard to say suddenly that I'm my brother, so I use my honorific name or call him my brother.
Yoon Kyun-sang said, "Kim Yoo-jung said, 'I will call you brother, please make me comfortable.'"
The members asked, "Are you two perfect friends?" Kim Yoo-jung said, "It is comfortable in the field now."
