Following the disbandment of 4minute, former member Sohyun wrote a letter for fans on the group's seventh anniversary.

The letter was written on June 16, the day they debuted and the day that their contracts came to an end, seven years later.

In the letter, Sohyun wrote, "I used to always say thank you on this day every year. But this time, I'm sorry and I'm hurting on the inside... Thank you and sorry so much to everyone who has been with us and showed us love for these past 7 years."

She ended the letter with a final message to her fan club: "Thank you 4NIA..."

Jiyoon also wrote a touching letter to fans, which she posted on her Instagram. The letter reads, "It's already been seven years since 4minute began. You all have made me so happy. I'm sorry that things didn't end in a more satisfying way, but I'll make it up. Why? Because I can't ever forget you. Please stay with us for a long time, just as the sky is always blue. I love you. Thank you very much."

Hyuna is the only 4minute member who has resigned with the label, Cube Entertainment. 

The four other former members of the group are focusing on pursuing other activities.
