but I am the first to say that it is perfectly normal that the manga has continued.
also because there are several subplots that have yet to be developed, primarily Ruka who is not a secondary character.
honestly, as much as I'm happy to read, this manga has several flaws (for now).
Yaemori seems to have been created solely and exclusively to intercept young fans of cosplay comics & games and above all to speed up the manga. basically yaemori comes and says "you love her; she loves you. love each other and finish it there"; it does not have a particular thickness.
on the contrary Sumi has the opposite effect, the character is interesting but it almost seems that he has been inserted to do a few more gags and to better understand what type Kazuya is. they made her fall in love with him but then it died almost at the same time she said it, it didn't develop.
Mami, in my opinion, is the worst (for how she has been used) ... in practice (at the moment) she is just a mcguffin; she doesn't have much use.
The only real problem if the manga was finished earlier is Ruka who is an important character for the story and for the characters of Kazuya and Chizuru; in a certain sense it is thanks to Ruka that Chizuru decided to go to dinner with the Kinoshita family and to make it clear what she was willing to do she asked where the altar of the dead was.
such a character could not have suddenly disappeared, not to mention that Ruka's physical problem that made her become the woman we know is still unknown to the other characters.
having said that I am not a lover of open endings.
when I saw the ending of the Ranma1 / 2 anime as a kid, I was disappointed.
however, I also can't deny that open endings have a bittersweet appeal.
and this time too I wrote as much as a university book. : D
