Sunmi left her group, Wonder Girls, in early 2010 to pursue an academic career and focus on her studies.
A New Path for Sunmi
In early 2010, Sunmi made the decision to depart from the highly successful K-pop girl group Wonder Girls. Her primary reason for leaving the active music scene at that time was to dedicate herself to an academic career. This significant step marked a transition from her demanding schedule as a performing artist to focusing on her personal educational goals.
Transition within Wonder Girls
Following Sunmi's departure, the Wonder Girls underwent a lineup change to maintain their momentum. Hyerim was introduced as her replacement prior to the worldwide release of the group's single "2 Different Tears" later that same year. This ensured a smooth transition for the group as they continued their global activities.
