I think what I find frustrating about this series is that it has the look of a serious introspective story. And I don't really mean the visuals, but I mean in the same way that there is "prestige tv" and oscar-bait films, this feels like the manga version of that. It only works because it's playing off of the expectation that things are happening in between the chapters, emotions and resolutions are occurring for the characters in the spaces in between what we see. And that approach is so incredibly difficult to pull off that, like here, it instead comes off as confused and the characters lack stability. Seven chapters into a story with ten chapters, as in 70% of the way through the story, I still know next to nothing about Hana or her motivations.
There comes a point where holding back is no longer sexy or mysterious, it's just poor writing.
That's a better way to put it that what I would have said. I don't mind stories with toxic and over dramatic characters like in My girlfriend is not here today, but here we have a serious and realistic setting with illogical/over dramatic (at least to me) characters. The two don't match up, which looks like poor writing indeed.
Seing Hana's point of view after all the actions that she did so far don't make any sense to me. It doesn't make me care about the character. If anything, I despise her even more.
Same for Hikaru. Love is built up on actions, not feelings. Of course it starts with feelings, but if your whole vision of someone is seeing through the lens of your childhood's feeling, without anything to back that up, that's very shallow. I really don't like that vision of love in media, were everything is attributed to feelings only. It makes me think of a quote I've read a long time ago "Love is a verb. Reactive people make it a feeling.".
