On February 9th, actress Yoo In Na guested on MBC Radio's "Blue Night, This is Jung Yeob" and shared her thoughts on working with Humming Urban Stereo for his latest digital single, "You That Day." She began, "I was worried about messing up the song, but I earned a better response than I thought, so I'm glad.  I felt my voice was a bit awkward at first, but listening to it more made me like it, and now I turn it up loudly in my room." The actress often talked about how she hoped to pursue a singing career, and so she was asked whether she wanted to join a particular girl group.  She replied, "It's probably impossible, but I'd like to join 2NE1." When asked to choose her ideal man, she chose actor Kim Kab Soo and explained, "Kim Kab Soo's acting is so moving.  My ideal man has since changed to him." The DJ mentioned how a lot of male celebrities (such as Lee Kwang Su, G-Dragon, and Lee Seo Jin) chose her as their ideal woman, and Yoo In Na shyly replied, "Their ideal women have probably all changed now." The actress was also asked about how she came to develop a friendship with IU, who's 10 years younger than her. Yoo In Na mused, "IU is mentally older.  An hour really isn't enough when we're complimenting each other, and I still haven't been able to find any of her flaws." Her guest appearance concluded with a heartwarming shoutout to her family members, after it was revealed that Yoo In Na worked hard for 10 years in order to reach her current level of fame.  "I don't have an amazing story to tell, like how my family was against my career choice, but my family did worry a lot about me."
