Megane-chan is one of those short manga that you can read during commute or a lunch break. With only 9 chapters, this title doesn't offer any meaningful story and is mostly comedy with some ecchi thrown in. Being seinen manga, ecchi content is natural and doesn't feel forced.
While cast is very small, the only character worth mentioning is the protagonist: Kogane. Pretty much all comedy and characters interactions are made through her. Kogane herself is fun and her perverted jokes are, in my opinion, the strongest point of this manga.
Art, while not ugly, is on the weaker side. Simply put it's... simple. There is not many details in characters and even less in backgrounds. Scenes focused on showing character's bodies in more erotic way also felt lacking.

Overall, I can recommend this manga. Not because it's that good, but because there is just no reason to don't read it.
