On November 3, LABOUM's agency NH Media announced they had canceled their exclusive contract with Yulhee as she informed the label multiple times of her desire to leave the group and entertainment industry. Her full letter is as follows:
"Everyone! Hello, this is Yulhee.
The weather's getting colder these days, so please dress warm and be careful about colds. You were all probably surprised by the sudden news, but aside from my apologetic feelings, I'm writing this letter because I wanted to say something to our fans.
I'm very thankful for the past 3 years that I've spent as a member of LABOUM. I've made many precious memories with the fans and members. I laughed and I cried a lot during these past years, and I spent a lot of happy days wondering if I deserved so much love.
However, there was also a time that I went through a lot of emotional hardships, and I asked myself numerous questions and worried about my future. During that long period of time, I talked about my concerns with my members and people at the agency, and they've decided to respect my decision. I'm announcing with an apologetic heart that today is my last day as Yulhee of LABOUM.
Many of you were probably surprised by the sudden news, and I'm so sorry for disappointing fans when they've given me so much love. I'm sad I can't keep my promise to stay by your side, but looking back, I realized there have been so many moments that I won't forget. It must've been so difficult and painful for my fellow LABOUM members to accept my decision, so I feel very thankful and apologetic to them as well. I'll always support them.
It's my last moment as LABOUM's Yulhee, and I ask that you keep supporting my fellow members. I also hope you support my future as Kim Yulhee. To the fans, members, and Global H Media employees, thank you for the precious memories and experiences.
Finally, thank you to all those who loved and supported me. I won't forget you.
Written by Yulhee."
