I don't think Mumei's going to go away forever. I think she'll realize that her health and all the responsibilities while working under cover made streaming difficult for her. One is gone and if she can fix her throat the other problem is gone too. And if she actually does care about her fans, I can imagine leaving forever makes her feel that she's letting them down in a way. So I'm kinda picturing that after a long hiatus she'll be back to streaming in some fashion, even if it's only like a hobby or side hustle.
