The plot is pretty much cliche but it is so good! The angst, love, attraction!! I personally had quite a bit of fun reading it.
The characters are predictable and so is the flow of the plot but there is a comfort in that as well. It is also in a alt universe of "I'm banging my rivial in a parallel world" so you can see the main characters from there but older.
This manga just gives me good warm vibes and I love the pairs in the recent chapters so things are getting more and more spicey with each new chapter.
Honestly I would recommend giving it a shot I genuinely think anyone would like it.
The plot of this story is pretty basic. It's your average zombie apocalypse love story, just yaoi. The art style was, by far, the best element of this entire manga. I wasn't too much of a fan of Mishiba's character, but that is just out of my personal distaste for stubby looking hairstyles and boring personalities. It was nice to see a more burly looking 'man' for once, seeing as I have read so much BL set in high school. The characters didn't really grow on me at all. The only real character I had interest in was Chibasaki, I enjoyed his approach to every situation and was touched by the end of the story a bit.
Anyways, I only give this manga a 5/10 for the last two chapters that sort of made me feel something.
