I have a very conflicting opinion on this manga. On the one hand, I really enjoyed the older sister/mangaka artist and their relationship, while being very conflicted with the relationships b/w Aoi-Yuri-Sumire. I felt that there needed to be an actual epilogue, not just a panel or two showcasing a massive timeskip in the end. Yuri was okay as a character, but there were many times she annoyed me especially when she would never stand up for herself. Sumire straight-up annoyed me for the most part (I liked him near the end). While I understand he doesn't want to forget his one love Seri, he treated everyone else (mainly women) like trash. Similarly, their mother was god awful of a character (not her representation, but the deeds she did), especially towards Fuyou. I was also mad at how Aoi got written off in 2 sentences, and that he would meet his fated one 2 decades later - that just seems really cruel imo.
8/10 - I enjoyed this manga, but was very conflicted throughout its entirety (near the end, it was good). I would never re-read this manga, it is simply too long for what it was and got incredibly boring b/w chapters 30-45ish as it was the same plot repeated over and over again. Also, I didn't like the fact the Yuri never really changed her appearance - it would have been nice if she grew her hair longer or slimmed down in the 4 years gradually instead of loosing 12cm off her waist in 2 months (incredibly dangerous, and very unlikely in reality). Regardless, I would, however, still advise people to read it at least once and form their own opinion.
