Like other Ori Mita's works, Yamada to Shounen is a fluffy romance manga. There is not much going on in the story line but overflowing cuteness. If you're looking for a light read, this might be it.
Story: 7/10
The story is kept reasonably simple. There are 6 chapters + 2 extras. (The extras are essential.) No drama to stir things up. No slow build-up considering the two characters realize their feelings for each other early on. This manga truly utilizes all the elements of the Slice of Life genre.
Art: 9/10
I have always been a fan of Ori Mita's art style, so this comes as no surprise. No crazy detailed backgrounds; a lot of white space throughout the pages so it's easy on the eyes. Ori Mita truly shines in depicting characters' facial expressions and actions. You GET a lot just from the simple panels she drew.
Characters: 8/10
All the characters in this manga are likable and well-designed. Chihiro has great depth and sensitivity for a high school boy. You will also get to see Yamada-san trying to understand his feelings toward his first male partner.
Enjoyment: 8/10
This manga always leaves me with feelings every time I reread it. The right amount of lightheartedness just works so well. I appreciate it not trying to be edgy, considering how it does touch on the age gap topic.
I strongly recommend this to anyone who likes Shounen Ai, or just Romance in general.
