Jimiko na Watashi wa Iroke wo Dashitai

Koto Furukawa is a plain girl who is always staying in a corner of the classroom silently and without trying to stand out. A girl like her quietly held feelings for a boy named Yuuta Kishi, a game otaku. She would always get saved by the dependable Kishi-kun whenever it seemed like the boys from class would make a pass at her.

In order to keep a boy like him around, she ends up trying a "sexy approach" as a result of consulting her older sister, a gal. Kishi-kun isn't such a pervert — this is what she believed while she tries to get his gaze fixed on her thighs after unexpectedly shortening her skirt!?
