>>98437329The tweet isn't depressing at all, MTL just sucks.
The second line means that she's finished off stream work that she had to do, so now she's available to play on short notice. The first line is just an open invitation, and the 3rd line is just a politeness thing.
MTL doesn't understand etiquette so it translates the first and third line the same, but they aren't in reality.
If you wanted to translate it more charitably it would be something like
"Open call for impromptu monhun! I finished my work early so I'm free right now. Let's play!"
Obviously it's a tweet and not a discord dm because it's short notice at an odd hour and thus doesn't know who's available.
