"Someone has been blackmailing members of the Public Morals Club into resigning! Mafuyu and Hayasaka have figured out what got Akki and Okegawa to quit, but Yui rejoined the student council and they haven't seen him for days. Worried about their friend, they break into his room to find him. But Yui's defection wasn't coerced--and he's more determined than ever to protect Miyabi's interests! Will this be the end to more that just their friendship?!" -- from publisher's web site.
