New reader here, wondering what the update schedule is for this, currently looks like two chapters every two weeks.
Also, are they caught up to the official release? I think we're a bit behind. Navigating a site in a language you don't know even slightly is difficult.
As for the chapter itself: I agree with the sister, no need to add more family members. And now that she's mentioned it I have to ask: why were they even living in a home with room to spare for two new family members? Did their parents leave a giant bank account for their inheritance?
Lastly we have the two uncles. Their future might've been brighter had they not gone to spy on Mu Mu, now that they have I doubt they'll leave unscathed.
