"We are writing to let you know that Dal Shabet members Serri, Ahyoung, and Subin's contracts have ended.Their exclusive contracts with Happy Face Entertainment will end in 2017. They will be leaving Happy Face Entertainment to show more charms they have that they could not show while being Dal Shabet members," the agency's statement read.

The agency said this "does not mean that Dal Shabet is disbanding. All the members are currently discussing openly about Dal Shabet, and we will let fans know when details are set."

It added that there was no bad blood with the three members and "we have built fondness and memories as family. We are more than a little sad to see the members that we have been together with for a while, go."

Dal Shabet debuted in 2011 and bagged the best new artist award at the Golden Disk Awards held in 2012.

Following the announcement, the three posted handwritten letters for fans to explain their departure.

"I debuted in high school and now I'm an adult. It is not enough to say thank you to the Dal Shabet sisters and Happyface family members. I spent the last seven years relying, improving, learning, and sharing a lot with you and I owe you all so much." wrote Subin.

Serri said, "My heart is heavy every time I have to write a handwritten letter. Now, I want to carefully talk about not our end but a new beginning. My contract with Happyface Entertainment ended in October."
