The show jumps around too much, it skips through dialogue that hopefully was included in the manga. I enjoyed watching it but wouldn’t recommend it to anyone unless you have nothing left to watch or do.
I don’t mind that it’s a romance between two men, I just really dislike the way the story is so chopped up. Take a little more time to develop the story, if 12 episodes is not enough time to do it, then make more. Best to do it right than have people walk away with people wondering if they understand what they just watched.
