Jiang Sung-hoon, a member of the Crystal Boys who has previously been on the topic because of many controversies, missed the Crystal Boys concert last September after many incidents broke out, making many fans worry about whether he will leave the group.
On January 1, Kang Sung-hoon published an article titled "Official Position" at his official fan club, Hoony World, in which he revealed his future whereabouts.
Jiang Sung-hoon wrote in the article, "Because of the constant occurrence of unexpected misunderstandings, I will be extra cautious when taking a stand." He also said about the Crystal Boy, "Because of the problem of mental health, I thought that postponing the Crystal Boy's activities would cause a lot of trouble for the group, and after repeated consideration, I negotiated with YG Entertainment to terminate the exclusive contract on December 31, 2018."
He also apologized to the fans who had been waiting for him for a long time, writing, "Although it has been in a blank period for a long time, I am really sorry for disappointing the fans who have not forgotten me and have been waiting for me." I also sincerely apologize to the members of the Crystal Boys for the loss caused by something related to me."
Finally, he said, "Thank you for your long-term support of Crystal Boy Kang Sung-hoon, and I also hope that you will continue to help the Members of crystal boy for their future activities, and once again sincerely apologize, thank you." YG Entertainment also confirmed that it officially terminated the exclusive contract with Jiang Sung-hoon.
A few days ago, the members released a photo of SECHSKIES 2019 SEASON'S GREETINGS on Instagram, but there were only four members in the photo, and many fans left messages asking "What about Kang Sung-hoon?"
Later, more fans found that Kang Sung-hoon's personal Instagram not only closed YG Entertainment President Leung Hyun-seok, but also the members of the Crystal Boys. Since the personal fan meet-and-greet last September, when he was embroiled in the controversy of cheating and deceiving fans, Kang Sung-hoon has never participated in the Crystal Boys' group activities.
In 2016, the Crystal Boys re-integrated through the variety show "Infinite Challenge", and then signed an exclusive contract with YG Entertainment, after Kang Sung-hoon stopped group activities, the remaining four people, Yin Zhiyuan, Lee Jae-jin, Kim Jae-deok and Jang Shui-won, continue group activities.
