Luckily eternal fansub is subbing this drama, and it's currently at episode 9, release some time this month, so that means episode 10 and 11 will probably be released shortly.
I didn't like ep 1 because it was slow and boring like someone said, but once you get past episode 1, it's a lot better, and I really mean it. The storyline is about the ordinary lives of people in a small town, a poor family, although the mother has an illness the family is still full of laughter. It's really touching. Not extremely dramatic (I'm watching ep 3) because that's not what it's about.
Ayase is good like usual, I don't think Ichihara Hayato is an exceptional actor (yet) but in this series his character's supposed to be a very rough guy who has "a strong sense of justice" (quote from the mother). So no, I don't think he's overreacting at all.
