After the sad news of the band's acoustic collaboration vocalist Cho Soo-jin was belatedly reported, the behind-the-scenes story of the deceased in his life is also being re-examined.
On the 27th, the agency Panic Button said, "Mosu-jin left us on the 25th," adding, "Depending on the will of the bereaved family, we decided not to disclose details including the cause of the death of the deceased." I hope everyone will mourn quietly so that the last path of the deceased is peaceful," he said.
Since then, Ko's Instagram account has been closed as of the 29th. Since then, the account of the cat, which is believed to have been raised by the deceased during his lifetime, has also been converted to private.
Acoustic Collabo has had three member changes, including vocals, since its debut with "Love is The Key" in November 2010. He started as a one-man band of Kim Seung-jae, but after 2nd vocalist Anda Eun Kim Kyu-nyeon, Cho Soo-jin was listed as a member. At that time, the competition rate was known to be 1,600 to 1.
However, they entered a long court battle in 2022 after having a dispute with their agency, and in 2024, the 24th Civil Affairs Department of the Seoul Central District Court ruled in their favor. At the time, the court said, "The exclusive contract was terminated due to the failure of the agency's settlement obligations and the resulting breakdown of the trust relationship, and the agency must pay the artists unpaid settlement and damages. "We will also reject all claims against the agency's artists for penalties," he said.
The lawsuit had been resumed after Acoustic Collabo filed a provisional injunction to suspend the validity of the exclusive contract in 2023 after more than a year had not been set since it filed against the agency in 2022.
The court said, "The provisions that the CEO of the agency runs a separate video production company, inflates the cost of producing the music video in the name of the above company, and do not object to it even if it is used as the cost of producing the album are invalid because they violate good manners and other social order." "It has reached a point where it is difficult to maintain the exclusive contract relationship as the mutual trust between the artists and the agency has been broken due to the failure of the agency's settlement obligations, and the artists' notification of the termination of the exclusive contract is legal."
"The agency is obligated to pay the artists unpaid settlements, down payments and delayed damages," he said. "Pay alimony, acknowledging the special circumstances that artists suffered irreparable mental pain."
After a tough fight, Acoustic Collabo signed an exclusive contract with its new agency Panic Burton in 2025 and resumed its activities. In June 2025, Cho released a single "Your Universe" under his real name Cho Soo-jin and announced his comeback, and said, "I'm releasing my first meaningful song with my new agency."
Regarding joining the 3rd Acoustic Collabo vocal, Cho Soo-jin, who had an interview with Star News in November 2020, said, "I thought I might be criticized a lot for thinking that I could be compared to my previous vocals. "I wanted the musicality of acoustic collabo and I liked it a lot, but I didn't try to imitate the tone or musicality of my previous vocals," he said.
The deceased started preparing as an idol trainee, but felt limited in his poor dance skills and was able to solidify his direction in vocal practice, contrary to the musicality of the acoustic collabo he listened to with the advice of his vocal teacher while preoccupied with his preparation as a vocalist. In the meantime, the copy video of Acoustic Collabo posting a hashtag on social media without even knowing the audition notice came to the attention of the company officials, and Cho Soo-jin, who eventually auditioned, joined Acoustic Collabo as the 3rd vocal member through a competition ratio of nearly 1,600 to 1. Cho Soo-jin said, "I've achieved my dream," but added, "I've been worried a lot."
After working together for about a year, Kim Seung-jae and Cho Soo-jin said they have been giving and receiving help to each other. Kim Seung-jae learned the part of trendy musicality from Cho Soo-jin, and Cho Soo-jin learned various virtues to know as a senior musician from Kim Seung-jae.
"There were a lot of things I didn't know while working in this industry, but thank you for taking care of me and accepting me one by one. I think it would have been really hard if I hadn't met my brother." (Mo Soo-jin)
"I tend to rely on this friend, too. Songs become very important because popular music itself becomes the base of songs. As I get older, I gradually move away from the trend, and I think I can know the trend more easily through Sujin and study. He's a friend who helps me grow up." (Kim Seung-jae)
In addition, Kim Seung-jae responded to questions about the beautiful but not-so-beautiful breakup with the second-term member and the conflict in the process.
"There are rumors that the team disappeared and the name changed after being discharged from the military. I really thought a lot about what to do. Nevertheless, what I thought was that even if it was a team that I started, I wanted to finish it, and I thought I had to carry it even if it was a bad (bad) situation. I thought that the more good music you hear, the better it is, and in the end, from my point of view, let's make a focus. Of course, there will be criticism against us, but I think we should accept it humbly." (Kim Seung-jae)
