>>11420522Miko's 1 million celebration project was the elite cafe thing they had in Akiba. Pekora was crying earlier this year on stream because her project was denied by manager, even though another Holo was doing something very similar.
People talk about late last year, but they performed PekoMiko Daisensou at Bloom earlier this year, so they were still on good terms for a while into 2021. I think this is the real reason, Pekora is salty Miko got to do something and she didn't.
She doesn't hate Miko for it, of course, so they still talk to each other normally when they have to, like in that Mario Kart collab, but she resents her enough to keep her distance.
The rape did happen, but wasn't the reason. Pekora enjoyed the sex.
