"Number Two really is Mazao's friend!"
"Am I dreaming right now? Although this place indeed is a dream realm..."
Mazao would never imagine that I could actually contact her long-lost friend from the future. She probably never even thought to reach out. It's not because she doesn't care about her friends but because the idea itself is blind to her.
It's just like the protagonists in web novels about rebirth who often don't consider whether the world from their future would continue to exist or how it could develop after they've been reborn into the past. If you ask them if they want to talk to the people living in their original future, they might be intrigued; if not, they might not even have the idea. Even if they do think of it, they can't seriously treat it as a realistic question.
I deliberately asked out loud, "Are you the little girl Mazao mentioned, the one who was paired up with her?"
