>>4240188This is partially right. It's true that she's in madly in love and only realized it (fully) too late. However, she never confessed, and that's exactly the issue.
Basically, the tsundere act was mandated by Cover. They know teasing a possible relationship is more enticing to the fans, and it's also adds a layer of plausible deniability, since a real lesbian couple could turn off some of the fans. But Mori herself has been using that to try and maintain some distance from Kiara, because she was starting to fall more and more for her, which was a very strange and complicated feeling.
Then, after a few months apart, the loneliness finally hit her hard. She thought Kiara leaving would finally allow her to get over it, but it just made it worse. Right now, more than anything, she regrets not having being more honest, instead of trying to subtly push her away, afraid of her own feelings.
This is where THAT tweet comes in. That's what she wants to "redo". Turn back the clock and do it differently. Maybe have done more to keep her in Japan. Been more open. Told the truth. To herself, and to Kiara. She regrets it so much.
So that's the reason for her break. In short, Mori trying her best to convince herself to not do something REALLY stupid, like spending a ton of money on an impulse buy, especially with the current world situation. For that, she realizes she needs to spend some time as far away from anything related to Hololive as possible, so there's no chance of her thinking about Kiara.
