Amano Megumi Is Full of Openings!

Shindo Manabu is a student at a very prestigious high school whose goal is to get into Tokyo University. He studies constantly and tries to never lose sight of that goal. That is until his childhood friend, Amano Megumi, who goes to the same school starts to distract him. He originally only remembered her as the tomboy she was as a kid, until he notices how "developed" she has become. As these two get closer to each other, hilarity often ensues and subsequently, Manabu becomes more and more distracted from his goal of getting into Tokyo U.
