Baek Ah Yeon has released her sixth digital single, 'LIME (I'm So)' MV. 

Through her agency, Eden Entertainment, "I've been trying various styles of songs while contemplating which one would fit well for my comeback." She continued, "I made an effort to showcase a more chic side."

'LIME (I'm So)' is a dance track that she is releasing for the first time in 10 years since 'a Good Boy' in 2013. She added, "This new song, 'LIME (I'm So),' is the most pop-oriented and has a strong beat among my music, but it's a rather minimal song, so you can comfortably listen to it."
