[talk] Cha Eun-woo and Feder Elias' new collaboration song Hey Hello will be released on the 30th.

Cha Eun-woo and Feder Elias look great together in a two-shot. They're so cool. Their new collaboration song, Hey Hello, will be released on the 30th of this month.

Just looking at the backs of the two of you, I think you'll have really good chemistry. I'm looking forward to a cheerful song that's perfect for summer.
