>>14152966There is no rrat, only rumors. It's mostly traces left in places like lolcow, where minor idols were discussed. If you're familiar with the relationship between Jrcach and Kiara, then you know the deal, take it with a grain of salt.
The specific rumor being that Kiara disparaged Peari and other gaijin idols on her blog for any number of reasons only Kiara knows.
However, there was no hostility but more criticism, which anons took as jealousy because Peari was part of a successful idol group that she eventually dropped out of right before they got popular (there's certainly parallels to kawaii too).
Unfortunately, the idol business was cut throat and I personally believe that Kiara's actions were a symptom of that toxic competitive environment. That and she was and still is young.
I know only the bare minimum but I know enough to invalidate most of the rrats that put Kiara in a negative light.
What is certain is that Kiara and Peari are two of the more sane idols that were part of the culture during the 2010s.
