I'm going to tell you about how far I've read (chapter 40), so this will contain spoilers.

If you read the synopsis, doesn't it seems you something similar to some work from a while ago?
Exactly, follow Nisekoi's lead. Still, I don't feel that this is bad, so i'll go by parts:

-First point, art: I will be clear here: The best of manga without a doubt, is the art. I have been reading works by Yoshikawa Miki since Yamada-kun, and the evolution of his drawing is very noticeable, it is what is most enjoyed about Kakkou no Iinazuke, how well it is drawn.

-Second point, Story. This is disappointing, it's cliché, boring, and in a way you already know how the story is going to unfold unless something very unexpected happens, which I don't think so (I hope I regret it).
To give you the idea, in 40 chapters that I have been reading the manga, it is exasperating how the story has not advanced at all, each chapter
more boring than the previous one.

-Third point, characters: I've read a lot of junk romcoms, but i don't remember none with a combination of cheap characters like Kakkou no Iinazuke ... They don't bring any kind of interest to the reader, you could substitute by a potato , and they serve the same function. The MC is something that I already read 50 times, Erika is like Chitoge (nisekoi) without being aggressive, and Sachi is the typical brocon sister ... The only character that is worthwhile and introduces something """""new"""" is Hiro.


The work is typical romcom, if you like the genre you will follow it with no big problems, me, in my case, I started reading it from the Oneshot and by inertia I keep reading it ...
But I don't recommend it, I feel like there are hundreds of similar works that are better.
