Davichi's Lee Hae Ri revealed the difficulty she faced before debuting.

She appeared on the February 14th broadcast of 'Yoo Hee Yeol's Sketchbook' where she revealed: "I applied to major in music college but I got rejected twice. I thought I should make money so I auditioned for YG Entertainment. I was eliminated in the second round."

She continued, stating: "Afterwards I went to college to major in classical piano but I wasn't happy so I dropped out of school. The company connected me to Kang Min Kyung. After we debuted, we performed at so many events, around five to six a day. But since it was the beginning of my debut I didn't earn a lot of money."
