Review for Season 2:
Wow.
This is a beautiful romance. I'm awestruck by how good this anime was, because for me, it's probably up there among the best romance anime ever.
What surprised me was how well written the romance was. Both these characters are beautifully written and grow at a great pace throughout the show. The fact that they're both inspired by each other, is exactly what makes this romance so brilliant and somewhat rare. There's also a beautiful scene where they both tell each other how they changed each other's lives and made them who they are today.
Ichikawa's character writing impressed me the most. Even in S1, his character development was the standout feature for me. In S2, it picks up right where it left off, and doesn't drop pace at all. When you look back at the start of the show, it's hard to believe that Ichikawa used to be the way he was. His character development is paced so perfectly. There's so much to admire about him - the way he thinks, the way he learns about himself, the way he always wants to be better than he is today and the way he genuinely loves Yamada.
Another great feature about this anime was its pacing for the romance. The romance moves along at a great pace, throughout the show. It doesn't slow down once. Which is again rare in romance anime.
The direction is phenomenal. With a show this well written, the direction, animation and the soundtrack should be able to match that. And it certainly did. The director also directed Teasing Master Takagi San. And I remember that even in S3, every single episode was close to a masterpiece. I'd say it's the same case with Dangers in My Heart S2. A lot of that is because of the direction. The soundtrack is brilliant too and it really stands out during the build-ups of heartfelt moments.
Although, I will say this, this anime is very dramatic with its sweet or romantic moments. So if you're not in a certain type of mood during the first watch, you could easily perceive it as over-the-top. But you might change your mind when you revisit it.
Overall though, I thought this was a phenomenal romance and it really took me by surprise.
