Reading this book felt like reading a light-hearted but ultimately unmemorable contemporary yaoi manga. It was cute but didn't really leave a lasting impression. The MC being able to see emotions was a somewhat interesting idea that didn't actually go anywhere except leading to misunderstandings and honestly, I wasn't too terribly impressed with seeing the author repeatedly emphasize that the MC having synesthesia meant that his brain was broken and I was even less impressed when

kissing made it stop temporarily and sex somehow cured it? WTF

  but it was a pleasant way to pass the time. 
 Actually, I do have one more big gripe. The main reason these two don't get together right away is pretty ridiculous.

The ML had one relationship that ended in a break up when he was in his early twenties and immediately swore off love? It didn't even seem to be a particularly malicious break up, just two people who's life paths weren't converging. Yeah, okay. How terribly traumatized he is.
