Pre-debut 2Eyes was formed by
SidusHQ with
Hyun Jin-young as their producer. It was SidusHQ's first investment into a K-pop group since the short-lived girl group
LUV and the highly successful first-generation boy band
g.o.d. Prior to receiving their current name, the group was called "god5" () as they were modeled after the five-member g.o.d. Hyangsuk and Dasom had both competed in the
jTBC talent competition '
before joining SidusHQ. Hyerin was a former JYP Entertainment trainee. Daeun had been a dancer. Yeonjun, the youngest member, was the final member recruited and had been part of an unsuccessful duo called Spiel () before joining the KBS singing competition program ' where she was scouted by SidusHQ. Prior to their official debut, 2Eyes recorded their version of "Winter Love" (), one of the soundtracks of the critically acclaimed
SBS drama
That Winter, the Wind Blows. It was released in May 2013.
2013: Debut The group name was derived from the idea of the members communicating with the audience through their eyes. They then made their debut on June 20, 2013, performing their single "Don't Mess With Me" () on the
Mnet music program M Countdown. The single album and music video for "Don't Mess With Me" were released in July. The music video featured fellow SidusHQ artist, actor
Kim Woo-bin. Their debut drew much attention from critics as their management agency
SidusHQ was better known for managing some of South Korea's top actors and actresses rather than musicians. In September, their company SidusHQ received a complaint from the Swedish company Saltkråkan which owned the copyright to the character Pippi Longstocking over the group's use of the concept without permission. ==Members==
