It's not a secret that Rie lives in Sydney, she's mentioned it a few times on stream. And the dalgiwooyoo email doesn't really seem like a secret.
Anyway, I want to say something nice about Rie - her collab with Erina a few days ago playing Untitled Goose Game was really fun and didn't get nearly enough attention here. Yes, I know I'm late but I don't give a shit, good content is good content and sometimes life gets in the road of watching cute anime girls stream. I'm normally I'm not fussed on either Rie or Erina, but the collab is really fun - it's a fun game, and Erina and Rie have good collab energy while playing, and Rie is much more entertaining with someone to work with. I've said it often enough, Rie's strength is as a collab partner. Nothing wrong with that either, some of the best entertainment come in an ensemble group. She should try to do more.
