Chizuru's looks always give people the wrong idea. Men assume she's a dominant type, and submissive guys keep throwing themselves at her. But what she really wants is to be tied up and mercilessly teased. Drunk and frustrated, she vents about it to a friend at a bar... right as her coworker, Kobayashi, walks past. Did he just hear all that? She shrugs it off and keeps drinking -- until she wakes up bound in an unfamiliar room, completely at his mercy.
