I'm not sure if this is the girls or not, but the application was filed on February 10 this year, just a few days after the new name was announced. It was under the name Park Sung Man (companies often apply using someone else’s name first). What makes me think this might be them is because the classification codes, since they include ones typically used for idol groups, specifically the most important service classes: 35 (business) and 41 (entertainment)
Anyway, it's actually nothing since there's basically no info there. I just wanted to share my 3 a.m. discovery with yall since I can't sleep.
