Back in February, Hyorin began her 3-part single series with single #1 - "To Do List". The second installment of Hyorin's solo series is set for some time in mid-April, reports say, titled "Set Up Time". 

Furthermore, Hyorin is currently staying in the United States, working on her music, including producing and choreography practice. Once again, there will be no music show promotions for Hyorin's comeback.
