"Empathy" is a pair of collaboration singles between South Korean musicians Jung Yong-hwa of CNBLUE and Sunwoo Jung-a. Consisting of the songs "Hello" and "Fireworks", they were released on January 15, 2016, under FNC Entertainment and MagicStrawberry Sound, respectively. After the two independently wrote incomplete lyrics to separate songs with each other in mind, Jung reached out to Sunwoo for a collaboration. Deemed as "fate", Sunwoo accepted and the two agreed upon a "double collaboration". An acoustic ballad and dance-pop number, respectively, "Hello" and "Fireworks" both revolve around the theme of love. The songs received generally favorable reviews from music critics, who commended the vocal performance by Jung and Sunwoo. "Hello" peaked at number 45 on the Gaon Digital Chart; "Fireworks" failed to rank on that chart, but peaked at number 86 on the Download Chart.
