妹がラインを超えようと必死な件

My Younger Sister is Desperately Trying to Cross the Line

by にとろ

A story about an older brother and a younger sister. A lighthearted, silly banter between a slightly yandere sister and her totally average brother... wait, is this even a novel? I'm not entirely sure, but well, since a younger sister is in it, let me just classify it under the Rom-Com genre...
