Here is my Twitter thread and original Tiktok which better explain the situation.

CHECKMATE is a co-ed Kpop group under Grace Company Entertainment. They debuted on September 21st 2020 and have since had lots of problematic events happen to them, including unexplained member losses, mistreatment and plagiarism accusations.

The 2 female members opened up personal Instagram accounts in June with the permission of their company. However, 2 weeks later, the 2 male members went silent and haven't been seen since. The female members are very active which raises suspicions that the male members have left the group or been kicked out.

What makes this scarier is, in October, all content containing member Nason was deleted suddenly with no explanation. In December, the company finally gave in to the fans demands and released a statement saying that he had left the group.

I'm worried that these 2 members will leave, or even worse, be kicked out of their group.
Even if they end up leaving the group, I want reassurance and communication with the company. If this situation gets enough attention, Grace Company Entertainment will have to release a statement.
