On May 26 episode of Mnet's television show 'TMI NEWS', YOON made a guest appearance.

YOON answered, "I'm not actually that concern about age. It's something that I honestly don't take into consideration when dating someone."
He continued, "I think I'll be okay about dating someone up to 20 years older than I am. I'm also okay about dating a girl who is younger than I am as long as she is not underage."

YOON said, "I want to have a small wedding. That's my dream wedding. I just want to invite my family and close friends."
When asked if how he wants to propose to his future wife-to-be, YOON said, "I want to do it really casually, like in an everyday life."
Jang Do-yeon responded, "Do you mean something like this? You just asking your girl, 'Hey, do you want to get married?' while having a stir-fry together?"
YOON laughed at Jang Do-yeon's witty response, and commented, "Yes, it's probably something like that."
