I kinda understand why hayami is uncomfortable with having sex while in his house with all the fishes since I'm also a pet owner (I owned a cat so yeah). I also like how the misunderstanding in this story is short-live and mostly are cleared in a single chapter (it saves me from another heart attack as someone that have a soft heart). Other than that, I liked how hajime didn't take taking care of fish lightly and research properly on how to care for them after he got told of the first time. Also, I like watching how passion hayami is in taking care of fish (and also hajime!).
