>>1557588Polka and Nene being packaged as a pair was a management idea meant to help boost Nene, who was underperforming at the time, with Polka, who has rebounded from Gen 5's rocky start and had stable growth.
This became unnecessary once Nene got her redesign. She's now growing steadily on her own, and management clearly wishes to present her brand independently now rather than along with a genmate.
Same reason Gurame cut down on their collabs together after a while. Collabing is great but when two people are packaged together too much, they start to feel like a package deal and it harms their solo appeal as fans grow to identify them as part of a pair and expect it.
