事件はスカートの中で

Yunatsu Sakahara had a secret - a strange "sound" that only Yunatsu could hear. It is a "click" sound, like the clicking of a camera shutter, that she hears whenever someone pays strong attention to someone else. Yuuka's obsession with attracting attention to herself by playing the role of a clumsy, innocent heroine keep escalating! In her desire for even more attention, Yuuka comes up with a forbidden method: "exposing herself up her skirt"...? And what is the reason for that smile on the face of the mysterious girl who knows Yuuka's secret...? (Source: Comic Days, translated)
