I don't know, it's rated 9.1 but I'd give it 8.8 or 3.5/5 at most. It's cute, and easy to read which is one of the things I like in graphic novels, however, it's too sudden? There was a plot up until chapter 3, then it just became episodic, don't know if the author is just eager to get them together or they were just given 3 chapters to do their thing, nonetheless it could have been better, there are literal oneshots that are able to pull off convincing plotlines in just a chapter. I don't get what made the seme attracted to the uke or the uke to the seme, their devotion to each other seems to spurt out of nowhere, the little tensions here and there that the author tries to incorporate seems halfbaked and eventually fizzles away into an underwhelming subplot. Maybe it's because of translations issues, I'll give it that, still nothing exquisite, I like the art tho.
