This story was quite refreshing to read, it has some controversial subjects in it and deal with them wonderfully!
For example, a woman having a younger lover with quite some age gap. This one probably is more accepted now but having the woman look after and pay for him is generally frowned upon in society. But I like how the characters don't treat it like a big problem, because traditionally it is the man's job to pay and look after the woman but now there's gender equality so as long as both parties are happy why should it matter to them? Also the matter of 'pride' being the reason why woman can't be smart or superior in any way, that's absolutely stupid because if you love someone the most important thing would be being by their side, not your pride.
Another thing I liked was how innocent Sumire and Momo's relationship was, I think it's lovely to cohabitat with someone and support each other like family. But there's also the thing where they all love more than one person, if you can love more than one friend, more than one family, I don't see why you can't love more than one person. Granted it may be rare therefore not socially accepted but I believe that you can love more than one person at a point in time. I also like how Momo actually said that he likes Sumire's boyfriend as well, in fact the author basically describes Momo as bisexual and I think it's nice how the author is open minded and thought that far because that does fit Momo's personality.
Another thing is the height difference, Sumire is much taller but they're still a great couple, it just emphasizes how its not the physical appearance that one falls for. Momo being shorter also doesn't make him any less manly.
One thing I didn't like as much is that Sumire does give up her job, but the author takes it seriously and I'm trying to justify it to myself that its about making compromises for love and that she has chosen to continue because sshe's writing freelance and there's a chapter where she talks about how she only wants to write what she's interested in.
The characters all feel deep and well developed, the author definitely placed a lot of thought on them. Momo's character is one of my favorites, because I honestly love characters that always seem happy and lighthearted but they actually see all and know all. Like in Shakespeare the 'fools' are the ones that speak the truth.
The art is really nice, way nicer than the cover picture right now in fact.
The plot is heart touching and complex, it's definitely not shallow.
Overall, a really great and entertaining read!
