I finished this manga several months ago, but I can still recall it vividly and remember how I was elated whenever a new chapter was translated.
I found it on a random reddit thread and binged some 60 chapters in a day, since the plot simply hooked me.

Story: 9/10, the premise was interesting, and the plot never really got old. [SPOILER] I was wishing that Chihiro would get together with Yugami the entire time but still felt great even after they friendzoned each other.

Art: 9/10, in the earlier chapters it was simple, but I found it charming and it didn't really negatively affect my view of it. The art got better later.

Character: 10/10, the introduction and then development of each character's personality was very interesting, especially since the entire plot of the story revolves around Yugami's personality. Solid 10/10.

Enjoyment: It was a very fun slice of life, and probably one of the most enjoyable I've read. I was hooked the entire time and the humor was also pretty nice.

Overall: 10/10, I loved it for its plot, its lovable characters, its fun humor, and it's overall very solid and interesting. Fits great in the slice-of-life genre, the sports genre, and it does contain some romance, which really spices up the plot a bit.
