Honestly, I was more interested in Jin and Sango than Ran, even though she's the MC.
I love the art and the storyline was pretty good, I just couldn't get 100% behind Ran. You can't excuse her saying she's a kid because she has Hibi right next to her as an example. Also, that guy, he was such a creep and pedo, even if not knowingly, and the fact that no one comments on it other than the brother, and he doesn't mention it to others is really frustrating too. That guy never really changed, he was only nice to Ran cause he liked her and the apologies was because he was dying, I don't really buy it that he really changed in the end.
Like others said, some places felt somewhat rushed or weren't very well explained, but for me it didn't affect much the storyline so it was fine for me. Loved the ending and how Ran matured in the end, but it's really frustrating having to remember how and why she matured in the first place.
Overall I guess it was really good, it's just one of those mangas where you love everyone but the MC.
