I'm pretty damn torn on Michiru at this point. She's an incredibly selfish carefree soul who still tries to balance child-care, work and her own interests with....mediocre results to say the least. On the one hand, I've always been of the mind that if you bring a child into this world, you should do your damndest to care for them. On the other hand, I disagree with the sentiment that you should completely give up everything for the sake of your kid. Hell, she's worth some admiration considering how utterly impossible it is for Japanese women to have hobbies like being in a band while juggling child-care and work!
Also, the author did a really good work with Yuuta. I'm borderline 'scared' of children but my adoration for this kid is Nico-level o_o
