Solo artist Kim Jae Hwan appeared as a guest on the April 9 broadcast of 'Yoo Hee Yeol's Sketchbook', in light of his comeback with his 3rd mini album 'Change'!

On this day, Kim Jae Hwan delivered a stellar performance of his 3rd mini album title track "I Wouldn't Find You", as well as a cover of Bruno Mars, Anderson .Paak, and Silk Sonic's "Leave The Door Open"!

After his stages, Kim Jae Hwan sat down with MC Yoo Hee Yeol for an interview, where he got to share his shocked reaction after hearing "Leave The Door Open" for the first time ever. The singer recalled, "When I first heard this song, I was completely, completely shocked." MC Yoo Hee Yeol also agreed, "I thought I was gonna faint after listening to that song." 

Kim Jae Hwan continued, "It wasn't just me, and it wasn't just the public either. I'm sure that everyone who heard this song the first time, whether an ordinary person or someone in the music industry, they all fell down after hearing it. So after I heard the song the first time, I thought that I needed to cover it, no matter what. And I am the biggest fan of Bruno Mars. He is my role model. Whenever I'm in front of a camera, I send him a video message. I always say, 'Hyung, let's have coffee some time.'"

How did Kim Jae Hwan feel about covering such a difficult, rigorous song? He honestly told Yoo Hee Yeol, "I just felt this a minute ago, while I was singing on stage. While singing the first verse, I was like, 'This... is so hard'. Even while I was singing, in my head I was like, 'Should I just give up on the ad-lib parts later? Maybe in the second verse, when it's Bruno Mars's part, I should lower the key?'"

However, MC Yoo Hee Yeol assured Kim Jae Hwan that he did an excellent job of the Bruno Mars cover, and that the clip will probably become legendary. Check out Kim Jae Hwan's "Leave The Door Open" cover for yourself, above!
