I got caught up in a beast-man turn commotion from my sister's matchmaking meeting.

Mitra is a female scholar who makes her living excavating and researching ruins. At the ruins she investigates, she ends up excavating absolutely everything. Her excavated finds generally scatter trouble in their wake. The main victim of this is her younger sister. The title is probably from the older sister's one-sided perspective! Once you read it, you'll surely find yourself sympathizing with the younger sister—a story where no decent people appear except for the sister.
