Looks like they smashed the two separate Snow White fairy tales together and have Akai Ringo playing a double role as well (as Rose Red).

Her mother is as "evil" as Ringo is. She uses everything to her own advantage, likely using Ringo in the negotiations. They were in a upper-lower class housing before moving into the mansion. It was abundantly clear that Ringo's mother is the kind of mistress who forces the wife out.

Thankfully the episode had a happy ending.

Two small things that were notable was that Alice does indeed love her cousin, and Majo has a thin body and very large breasts (proportionally). Someone speculated earlier that Majo might be the real Mysterious Beauty, and they just may be correct.
