For ten years, it was just me and my father. After my mother passed away from illness, he raised me all on his own, and I could never thank him enough. One night, my father brought home his coworker, Ueda, to prepare for the company's founding anniversary party, where they were in charge of entertainment. My father, seeking advice from Ueda—who was known for livening things up—decided to organize a sexy quiz game, and soon grew increasingly excited about the idea. As their enthusiasm builds, an unexpected and twisted development begins to unfold between the two of them.
