Masato Kazama, a 26-year-old salaryman in a high-pressure advertising agency, leads a monotonous corporate life. His junior, the fresh graduate Nagisa Inami, embodies the ideal heroine with her beauty, style, and quick wit at work. Although amicable, Nagisa's excessive fondness for Masato shines through her constant invitations for post-work drinks, where her inebriated antics reveal a flirtatious side. As she blurs the lines between professional and personal, one wonders if her actions stem from a love for alcohol, transportation woes, youthful impulsiveness, or perhaps something deeper.
