4In his strangely intimate dreams, Sayo has been catching glimpses of Itsuki Mashiba's private life through the eyes of his beloved cat plushie, bringing the two boys a little bit closer. But someone isn't so pleased with this development: Itsuki's older brother! Not only has he taken the plushie hostage, but he's convinced that Sayo is in love with Itsuki, and he's dead set on keeping them apart by any means necessary--including kidnapping Sayo himself! Is this purely an act of spite, or does he want something more...?
