Gal Gohan comes off as your generic teacher x student romance comedy manga with a small twist, the main female interest being a gyaru. This review might be slightly biased due to the fact that I haven't read much romcom manga or watched much romcom anime as well but damn was Gal Gohan a wonderful read.

Story: The first 3/4 of the story revolves around her high school life, spending time with the teacher, Yabe in club activities and whatnot, as well as their experiences meeting the different characters such as Fujiwara and Ms.Shirahama. The last quarter involves several time-skips which may come off as confusing at first starting from a couple months after Miku's graduation to probably around 10 years into the future. Not to mention, Gal Gohan has its fair share of cliché depressing moments but it's still executed very well nonetheless.
Overall, the story is very solid, 8/10.

Art: The art is well drawn throughout the entirety of the manga, including multiple nicely drawn full page shots as well as fanservice chapter covers for us cultured folks. The art does actually drop in quality in a few scenes but I presume it was used to enhance the comedic effect of those scenes.
Overall, strong, appealing art, 8/10

Characters: There are essentially only 3 characters that are important to the story; Fujiwara, Miku, and Yabe. These 3 characters are exactly as you'd expect from a stereotypical teacher x student romance comedy, the rival, the main character, and the love interest of both of them. During the early chapters, none of the characters seem all that special and don't receive that much development either. But once Fujiwara's arc begins, get ready for a roller coaster ride of emotions. Miku and Fujiwara go from generic, mediocre characters to being very well developed, showing significant mental (and physical ( ͡° ͜ʖ ͡°)) growth during this arc. I can’t dive into details without revealing too many spoilers so I’ll just stop for now.
Overall, the characters received significant character development, and were made into very fine-tuned, somewhat believable characters. 9/10

Enjoyment: Similar to what I said in my explanation of the characters, Gal Gohan takes a generic romance comedy trope and executes it very well while still retaining a good portion of its trope’s stereotypes. While the art and story were very solid throughout the entire story, the combination between these two and the characters just created a perfect mixture of fun, lighthearted gyaru romance comedy manga. I’m not a big fan of the romance-comedy genre and I often get bored after reading a couple chapters but Gal Gohan managed to maintain my interest for its 4 years of serialization.
Overall, reading Gal Gohan was a very wonderful and enjoyable experience. 9/10

In Conclusion, Gal Gohan is a fun romance comedy manga that managed to interest me, someone who has little to no interest in the genre to continue to read it for an entire 4 years as it was getting serialized. Gal Gohan takes interesting concepts such as cooking and incorporates it into the manga, even using it as a major plot point during a certain arcs of the manga. As always, if you enjoy gyaru manga, this is a must read that cannot be skipped. All in all, I think Gal Gohan is a great manga to start off with if you want to dive into the romance comedy genre, and it was a very entertaining experience these past years reading it. I apologize if this review is written quite poorly as it’s my first time writing any sort of information/serious review.
