Although I liked the prequel, it's disheartening to know that all these girls who say they love the protagonist so much end up leaving him, it was like that with Anna, Lena, Rei, Lea, Jessica...
The fact that all of them left him and then returned to him years later is, to say the least, uncreative, if they love him so much, they wouldn't leave him unless they had no choice.
Anna left him because of something urgent in the family, but she returned to him as soon as she could.
I would love to see a remake of MNM; it’s better than leaving it in limbo, and still have the chance to improve it, for instance, something hard to accept is that this famous and wealthy architect lives in a small house with tiny bedrooms with such a big and close-knit family, it doesn't even have rooms for all the daughters...
It’s not something crucial, but a remake is an opportunity to "fix" details like that.
Anyway, Rei is my new favorite, I love her.
