To be quite honest, this volume was rather uneventful. We still don't necessarily know where Miyano stands on the possibility of a relationship between him and Sasaki. It's not frustrating that he's taking his time because it is a big decision and Miyano is exploring what it means to like another individual. He's also attempting to understand his sexuality. I simply believe that I came off of really enjoying volume 3 that I expected to have the same experience with volume 4. Unfortunately, that wasn't the case. I'm still going to continue on with the series, but I'm hoping to see more developments in volume 5.
