On December 30, High.D announced her departure in an Instagram post. 

The message states:

''Hello, this is High.D. ⠀
⠀
With the end of my contract with my first company TS Entertainment, which gave me a very precious time and memories to take the first step in my life, I would like to convey my heart to you in writing. ⠀
⠀
Thank you for leaving half of my twenties with warm enough memories as the cold winter begins at the end of December.⠀
It was said that I would bring you good news in the near future.
I'm just so sorry that I only delivered the news.⠀
Thank you for supporting me and sharing a lot of love during this time. ⠀
I will never forget it.⠀
As much as you have been waiting, I want to show you good steps in the future.⠀
There will be various days that you can't understand, but
Gradually, a person like that can fill
I try to make my days.⠀
I would like to greet you in the future as Kim Do-hee, who can repay the love she received from High.D of Sonamoo, who received undeserved love. ⠀
⠀
This is the last time I greet you in the name of High.D of Sonamoo.⠀
So far, it has been High.D from Sonamoo.
Thank you🤍''

High.D debuted as the main vocalist of girl group Sonamoo on December 29, 2014. With the departure being finalized, girl group Sonamoo has officially come to an end.
