Hints of the mystery are buried in an old collection of works of the former members of Classics Club. The collection is titled "Hyouka."

Mayumi Dojima, a second-year student at the exclusive Yubiwa Academy middle school, has lost something—a star she glimpsed just once, ten long years ago. But help is on the way, in the form of the unofficial, secretive, and thoroughly mysterious Pretty Boy Detective Club! Rumored to solve problems within the school (most of which they themselves might as well created) for reasons aesthetic rather than financial, these five gorgeous boys sweep Mayumi into their world of excitement, danger, and overwhelming beauty.

They're ordinary husband and wife realtors until she undergoes a dramatic change that sends them down a road of death and destruction. In a good way.
