I thoroughly enjoyed this drama. I started watching this in the last few weeks of it airing, and while I was waiting for the new episodes to come out, I'd rewatch earlier episodes multiple times because I liked it that much!

Apart from Kubota Sayu (Hori), the acting was really great all-round. Suzuka Ouji (Miyamura) did a really good job at playing his character - he became such a sympathetic character. All the sides did a great job. Kubota wasn't particularly bad, just not particularly good - in comparison to Suzuka, not very natural. But the romance and chemistry between them is awesome, and is definitely the highlight of the drama! I would've loved to see more of their relationship, and the side plots were all really interesting, would've been nice if they were explored more too.

The main fault with this drama is basically the last episode. I felt like a lot of side plots/conflicts were opened up in the sixth episode especially, but then they weren't really tied up by the final episode. Perhaps the writers tried to tie up some of these things in the sixth episode but they just weren't clear enough about it, hence it didn't feel finished. The next fault with the last episode was the classic unrealistic misunderstanding/communication issues that seem to be common in j-dramas - the whole series didn't have this, and it felt so natural and refreshing, but then this was basically the premise, out of nowhere, for the last episode.

BUT, I still DEFINITELY recommend this! I was a bit disappointed by the last episode, but I can definitely see myself rewatching the rest of the series again. It's pretty easy to think of the last episode as just a writing mishap and not really consider it canon.
I can't imagine a second season with the way they ended it but if they did I would be beside myself!
