CL gives no fucks and only cares about her promise to her fans, which she fulfilled on the last day of 2017/first day of 2018 (depending on your position in the globe).
CL revealed two posts on her Instagram about how she recorded a song and music video over a year ago and wasn’t able to release it. She didn’t even know if it would be released.
However, she had promised herself, and her fans, that she would release new music in 2017. This was her gift to us.
