In 2012, T-ara had a drop in popularity. The group was accused of disagreements and problems with one another. Soon after, Hwayoung left T-ara. Areum did the same a year after. After these issues, T-ara's albums and songs had mixed success in South Korea. As a result, T-ara changed their focus to China. In 2014, they made a cover of the Chopstick Brothers' song "Little Apple". After focusing on China, T-ara became one of the most popular K-pop groups in the country.
