>>6081078>says that either Lamy is doing something right that Polka isn't.it's moe. There are only four ways for an anime girl (be it live interactive like VTubers or scripted like regular anime) to succeed:
1) to make you wish she is your girlfriend
See: Lamy, Rushia, Zero Two
2) to make you wish she is your mommy
See: Choco, Mio, Senko San
3) to make you wish she is your daughter whose smile you would protect with your life
See: Haachama, Ayame, Kana (from Dragon Maid)
4) to make you wish she was your buddy
See: Coco, Calli
Failing that you have to have an actuat talent: singing, ASMR, entertaining well, playing interesting games, being good at zatsudans.
If you lack in ALL of that you're fucked and Polka (and Nene too up to a certain point) really need to step up because clock is ticking and the timing for them to find their niche is running out
