It seems NijiEN's manager is a huge boomer based on what Selen and Rosemi have said.
Apparently he/she recommended they play Roblox because it has very good analytics, and all 6 of them flat out rejected them on the spot. A shame, Pippa could have had some friends to bully children with.
On top of that, they've been revealing their debut lines that didn't make the cut (the ones from the PV). They all wrote their own but the manager gave them some prompts and they were all awful. Petra in particular took her time recording her lines because one of hers was 'Ice, Ice, Lady!' and she cringed so hard Selen had to tell her to record it so poorly so it couldn't be chosen for the final cut.
Finana and Rosemi also mentioned Wave 3, saying they're looking forward to them having to go through that phase before debut. It's the first time Wave 3 have been brought up by them.
Just thought it would be a funny tidbit to break up talk of the whole MeToo movement thing going on with VSHOJO.
