Mint is way more talkative on the extended patreon podcast.
Nothing too concrete.
She said she wanted to go to school. People rratted hard about that but it turned out she really did go take language classes in Japan, which are now over.
During the podcast recording itself Matara literally finds out that Mint was going to start streaming properly again, before that I guess it wasn't really decided. That would have been at most two weeks ago or so.
I'm listening to the behind the scenes patreon hour right now and it sounds like Mint was stupendously burnt out. Matara is saying she (Matara) went into it understanding she would have to do a lot of the setup work because Mint wasn't in the swing of things, and she (Mint) had said several times said she wouldn't be able to contribute much due to where she was mentally.
Reading between the lines it kind of sounds like Matara set a lot of stuff up so that Mint would have something to ease her back into things again, like, merch and patreon so Mint would have an income, organized her model updates, setting this up as Mint's job more or less. That's not outright stated though, just my read on it. Mint is a person with brainworms so heavy that she thought no one would member her, and thought she would need to take a grocery store job to get by.
