I really love these cute chapters, while it's kind of just filler right now, they're always so cute. I am happy that the prince is fine with Yvonne loving another girl, so we won't have to deal with that drama.
Though, l do know that eventually the villainous system will come back.(Probably) I mean the spell that caused the villainous system to disappear happened in the future, in an alternate timeline if you will, but now they're in the timeline where Elsa and Yvonne had met when they were children. I think because of the fact that Yvonne came from another world, the villainous system manifested into her body because she has to play the role of the villainous. Eventually I don't know when but it will eventually come back,(probably, then again the future Elsa had no problem entering the past world so maybe the villainous system not working occurs in every alternate timeline that Yvonne has consciousness in?) and honestly I don't think I could handle the villainous actions happening to young Elsa, even if it's in the funny chapters 2-20 way. As we can see that through two incidents that occurred in the story (in chapter 1, and in chapter 28), the villainous system is still very harmful.
I really need to reread pbmmv again I love the series so much. I wish this series had even more fans so that I could talk more on this subject
Edit: Actually in chapter 56 you can see kind of the villainous chain breaking when Elsa and Yvonne kiss so if you want you can interpret the kiss breaking the chains the villainous system had over Yvonne. Though I still believe that it can either go down the villainous system coming back route or just cute kids doing cute things no drama route.
