On one hand, I like the realistic development of Matsunaga and Miko's relationship. With them not living together, it makes sense that there would be more of a disconnect and difficulty in lining up schedules. At the same time, I also feel like a large portion of the big blow-up is a direct result of Miko's inexperience and youngness.  With a bit more life experiences in her, it wouldn't have felt like the end of the world for those events to happen. They shouldn't for sure, and Matsunaga no doubt messed up, but Miko's reaction is directly correlated to her age, and it just make the contrast between them that much starker. I've also said this before, but I still really dislike Ryo's role in this whole thing. I don't think he was a necessary addition, and I would have preferred Miko rely on a female friend to help sort out her feelings in this instance.
