Crush recently appeared as a guest on singer Sung Si Kyung's YouTube channel in light of the release of his 3rd full album, 'wonderego'. 

Each week on his YouTube channel, Sung Si Kyung invites his colleagues to dinner and drinks, cooking whatever food his guests wish to eat that day. This week, Crush chose soybean paste jeongol and seafood pancakes.

After setting the table, Sung Si Kyung commented, "I listened to the album. It's really good. Did you write all of it? It's different from your last album, but then I see that there is a certain melody line that you prefer."

The singer continued to praise, saying, "It made me think, there is a pop star like him in Korea. I wish you would become even more famous. More famous than Cha Eun Woo. And all the children will say that they want to be like crush, and not a K-Pop idol." 

While Crush was speechless from the barrage of compliments, Sung Si Kyung pointed out, "Idols are great and all, but all the kids these days want to be an idol. But what if they say, 'Oh, I don't have to be an idol. I can become a successful artist and then just date one. There's always that option'," making Crush laugh.
