blaming that on the writing is kinda crazy. that's just how humans are sometimes and it's actually a good indicator that an author has a good hold on human emotions...
The writer is making the audience root for the two people to get together and raise the child as a salvation moment despite both of them not being qualified. Also the raising part treated as their character development, second chance at romance and almost salvation moment.
The emotions portrayed are good because it's from the adults' POV and not the child's. If it was from her POV we would have hated every single adult in the story.
The author is trying to capture humanity in imperfections. Which writing wise is fine I guess.
? the writer is actually directly telling you that both of those guys are not qualified did you just skip like... most of the dialogue? the recent chapter even has one of them and the granny talking about it. even the title says it - they're dysfunctional. that's the point. the author ain't promoting anything
I would have liked Ririko if she didn't keep the child actually. This manga meant to be a serio-comic but if you see it from the child's perspective it's traumatising. It was not her fault she was born and now she is being juggled around by irresponsible adults. I don't blame the MC or the ML for not wanting to take responsibility because that's how responsible adults do. Their lives are shit and forcing child rearing is not character development, it's like Indian mothers getting their sons married to tie them to their house and the wives and kids suffer.
Ririko could have easily @borted but she didn't because she is quirky like.....what the fuck? The writing of this manga is in shambles.
