Ha Sung Woon discussed promoting solo after Wanna One.

On the February 28th episode of 'Idol Radio', Ha Sung Woon talked about his solo debut track "Bird", saying, "There are so many things that are harder now that I'm solo, so I think I have to study in the future too. The most difficult part was thinking about performance too. I want to be reborn after becoming a bird and flying to the top. Those who gave me wings are those who love me and mean to fly above the summit."

He continued, "I feel that Sky (Ha Sung Woon's fandom) suffers more and cares about me more than I do."
