To celebrate South Korea's National Parents' Day a little early, BTOB member Hyunsik and his father/veteran singer Lim Ji Hoon appeared as a duo on 'Yoo Hee Yeol's Sketchbook'!

On this day, Hyunsik and his father performed a heartwarming duet of Lim Ji Hoon's hit song, "Reminiscence". Afterward, during their interview segment with MC Yoo Hee Yeol, the father and son showcased a comfortable chemistry, charming the audience. In particular, Hyunsik revealed regarding his relationship with his father, "We still kiss each other on the cheeks. But since it's Parents' Day, I would not mind giving him a kiss on the lips." 

However, hearing this, Hyunsik's father seemed strongly against this idea, shaking his head as he remarked, "He really changed after becoming a member of BTOB." 

Well, how did Lim Ji Hoon react when his son said he wanted to become a singer, like him? Lim Ji Hoon stated that he had been very against it, reflecting, "As a father, I felt that he would go through much heart ache if he chose this path. It is not an easy path to take." But Hyunsik replied to this with, "Well, at the time, I was at the peak of my puberty, so I didn't listen to my father. I started a band secretly with my friends." 

Afterward, MC Yoo Hee Yeol also asked Lim Ji Hoon to sing a snippet of another of his hit songs, "The Ebb of Love". Check out clips from this week's broadcast of 'Yoo Hee Yeol's Sketchbook' with guests BTOB's Hyunsik and Lim Ji Hoon, above and below!
