One of the better gyaru mangas. Focuses on normal day scenarios in school, not too ecchi and Kuro gal is really cute. Even though it seems like the otaku boy would be a love interest at first, this is definitely a yuri manga.
The phasing is equivalent of a gag manga, which means that the characters and the story stay a bit shallow personality-wise. A couple of unnecessary characters are introduced in the end but their chapters are really short. Art style is good with minor perspective flaws. Readable in a day.
This is no Kuragehime but it brought a smile to my face.
