I'm writing a review because I don't plan on reading any more. I've only read up to chapter 18, so this is my opinion on them. It wasn't what I expected. What I thought it would be was Hikari developing her story. It starts like that and I identified with it right away. The thing is: she has a secondary character complex and feels bad about it. So, in her own manga, she becomes a secondary character. I don't mind developing other characters besides the main one, but the impression it gives is that she's not the main character. Maybe that's exactly what it is andI misunderstood.
If that's the case, I still didn't like it because this alternation from one character to another doesn't work very well. They're sad and dramatic stories, but they only have 2 chapters to develop them, so you don't get too attached. Something that also irritates me is wanting to know more about a story, but I have to wait 10 chapters because the author decided to show the POV of other characters. There's no focus and I don't like that.

They're all tragic love stories, but I can't sympathize with all of them, not only because they don't have focus, but because I didn't like all of the characters. So it's hard to root for them. I don't understand this, if the story was about Hikari, I would have liked it more. I have mixed feelings about this manga because I saw potential, I started liking it and I like some of the stories, I just couldn't like how they're told.
