As you can see - I have rated this manga very low. It's a very typical manga. And not very enjoyable.

Story 4/10:

This manga is a very slow-paced story. It's a typical story where the girl doesn't understand the male protagonist's feelings and starts to realize her feelings very, very slowly. The romance is very slow and really get anywhere. Interesting romance really only happens at the end of the manga, which happens a lot in the manga I have read. The story is pretty boring and nothing really romantic throughout most of the story happens.

Art 7/10:

I really enjoyed the art style and thought it was very nice. The artist is very talented. I really don't have a lot to say though.

Character 6/10:

The characters weren't really that special to me. They didn't have a lot of originality and depth. It's a typical smart, quiet, ice girl and nobody knows anything about her except for Yagani.

Enjoyment 5/10:

I enjoyed the end, but nothing else really entertained me. There was some comedy and romantic parts. I don't enjoy slow-paced anime or manga. I feel like I waste my time and the story doesn't really get anywhere.

Overall 6/10

It was a meh manga. I have read better but also read worse. This is a great manga for people looking for calm manga.
TL;DR Story was slow-paced, not much romance. Art was pretty decent.
Characters didn't have a lot of development in my opinion. Enjoyment for me was at the end of the manga.
