Popular Group Suffer 80% Drop In Album Sales After Multiple Members Leave 

It was a massive shock.

Since their debut, ZEROBASEONE had built one of the most consistent sales records in K-Pop history. Almost every album they released as a nine-member group sold over one million copies on the first day.

So when their new five-member lineup dropped Ascend, fans were watching the numbers closely. The result? 198,045 copies on day one.

It was a massive shock. Their previous lowest first-day figure was Blue Paradise at 1,013,921, which means Ascend sold roughly 80% fewer copies than their last release as a 9-member group. Even the most cautious fans had expected at least 500,000.

The group reorganized earlier this year after Zhang Hao, Ricky, Kim Gyuvin, and Han Yujin all departed when their contracts expired in March 2026.

The five remaining members, Sung Hanbin, Kim Jiwoong, Seok Matthew, Kim Taerae, and Park Gunwook, chose to continue under the ZEROBASEONE name.

And now, with numbers like these, netizens are split on what actually caused the drop: the loss of four members and their fanbases, or simply a logistics issue with pre-orders not being processed in time.

• “I thought it would sell at least 500k, looks tough”
• “My pre-order hasn’t even had a tracking number printed yet.”
• “Wow, did all the international fans leave?”
• “The basic version tracking numbers haven’t all been processed yet. 150,000 of those counted are just the digipak mini version stock. Please hurry up and send the tracking numbers… mine hasn’t shown up yet”
• “Weren’t there supposed to be 4 versions?”
