Maybe it's because it came so easily to her in the beginning on youtube. She expects every venture to be like that, and when it's not, she's shocked and just quits.
Yes, she expects everything to fall into place like it had done in the past with youtube and her engagement with Joe (he was desperate for a long term gf and Charlotte passed him on)
Niomi hasn't faced any setbacks before and it's hitting her hard. Life can be hard Niomi, that doesn't always mean following the path of least resistance if it's leading to somewhere you don't ultimately want to be
There are many woo, spiritual accounts doing well on tiktok but with nioni it doesn't seem genuine, and her follower base aren't interested in it, therefore it hasn't taken off. They want Niomi's wieiad, vegan recipe book try outs, cruelty free lifestyle products and sedate holiday vlogs in Tuscany not naked mud wrestling at a festival and cock worship retreats with partner swapping. You have to know your auidence!
(Personally I like all the drama, so i hope they share the wedding, but... I'm probably in the minority)
