In somewhat of a surprise announcement, at least to me, Shofar Music revealed that Ji Yoon would be leaving the duo Bolbbalgan4 and Ahn Ji Young would continue on using the name (brand, really) as a soloist.
“Member Woo Ji Yoon has expressed her desire to wrap up promoting as part of BOL4 due to personal concerns about her future career, and we have had several meetings to think about the matter carefully with the members. After speaking with each other for a long time, the members came to understand each other’s thoughts, and Shofar Music also respects Woo Ji Yoon’s decision, so we have come to the following conclusion. BOL4 will now be a one-member artist with Ahn Ji Young and no additional members. After contemplation, Woo Ji Yoon has decided to wrap up promoting as BOL4. We, Shofar Music, are also sad that BOL4 will not be able to continue on together, but we have made this decision to respect and support [Woo Ji Yoon’s] thoughts more than anything else. Moreover, although Ahn Ji Young and Woo Ji Yoon will wrap up promoting together as part of a duo, they will continue to be colleagues and friends who support the paths they each take.”
Ji Yoon also wrote a letter about her decision, essentially reiterating that it’s about her goals.
As a casual listener of the group that enjoyed some of their songs, this is rather surprising as they seemed to be in the prime of their careers and popularity. However, seeing some fans react to the news, it appears Ahn Ji Young had always been getting most of the focus in their promotions, so it was a bit less shocking for them that Ji Yoon wanted to forge her own path.
