Honestly I'm not sure why this was categorized as shounen because for me I am considering this as shoujo manga.
One of the reasons why I was hesitating to read it at first because I thought it was a harem manga or something since I was focusing too much on the "shounen" part and I don't really read summary or synopsis so I really have no idea what's this manga all about.
Don't get me wrong, I love shounen manga myself but I love it more if the protagonist is male (I read anything btw. Be it shounen, shoujo, yaoi/BL, josei, seinen. As long as the story and art piques my interest.) But nevertheless I tried reading this one day and WOAH.
Story: 9/10
Tbh I don't really see anything unique about the plot... just your typical high school romance story but for some reason I really love it. It's simple and nothing complicated and really cute and adorable! And what makes this manga super interesting is the humor! It was unbelievably funny.
Art: 10/10
The art is really good. Another reason what made me read this manga. It's beautiful, gorgeous, pretty, amazing.. I can't even describe the love I have for the art. And did I ever mention the male protagonist, Miyamura, is such a cutie?!
Characters: 10/10
The characters will make you love the manga entirely. Like I said, the story is just your typical high school romance stories but because of the characters, it exceeded my expectations of this manga. The female protagonist, Hori, that I thought will annoy me even before I read the manga is now one of my fave female characters! And of course, Miyamura, is one of my ideal shounen boyfriends. Just ugh. I love him.
Enjoyment/Overall: 10/10 / 9/10
I was actually torn between 9 & 10. I gave it 10 for enjoyment because I really did (super) enjoy it. It is something that I'm looking forward every update of the chapter.
And I gave it 9 for overall because I'm sure this can get even more better in later chapters (and I hope the quality of the story will not drop) so I'm really looking forward to it. That said, I think this manga has everything to offer if you're looking for something Boy x Girl romances... humor, interesting plot, beautiful art, lovable and unpredictable characters!
EDIT AS OF MAY 9 , 2018
I'm not gonna delete my previous review but I just had to add this after getting caught up with the lates chapters. Wow, happened to Hori? In my previous review, I said what I love about this are the characters but Hori's character development became so horrible. Just what happened?! She was one of my faves but she became so terrible. She became too violent it's not even funny anymore. She's being unreasonable and her jealousy is too extreme. She always hit Miyamura and even if it's for comedic purposes, I DON'T FIND THAT FUNNY AT ALL. I miss the old Horimiya :(
