I found it very curious to see a group called Billie with 3 letters L and the comparison to Weekly with 3 letters E is unavoidable.
Are we reaching a point in which the producers just don't have any other options for naming their groups?
No hate towards any of the groups mentioned, since the group name issue is actually big among 4th gen groups (not that the other gens were any better, with the 3rd gen being all about numbers, for example).
