[3][17] In a later interview, CEO Lee Joowon said that he believed Minx had failed because there were too many K-pop girl groups promoting at that time with a similar "cute" concept and music style.

[18] Its lead single "Chase Me" is described as a "young metal number based on a rock sound," steering away completely from Minx's former musical style.

[23] Dreamcatcher released their first EP, Prequel, on July 27, with the lead single "Fly High",[24] a "dramatic song with powerful guitar sounds that opens with a beautiful piano melody".

[94] Dreamcatcher reached number one on Billboard's Next Big Sound chart for the week of February 13, becoming the first K-pop girl group to do so.
