Azu and Junpei finally manage to smooth things over. But then, photos of Azu's night with Kuroi surface, taking the couple back to square one.
While struggling to come to terms with Azu's own infidelity, multi-time cheater Junpei once again comes face to face with jealous ex-lover Rina.
A rumor spreads about Junpei's infidelity but is quashed by Rina's denial. While relieved, Junpei can't quite shake the feeling that something's off.
