Habahiro Hige is a simple-minded elderly guy who works in an office and enjoys Tabekko Marshmallows. His days are frequently spent being taunted by his 24-year-old coworker Iori Wakabayashi, who takes advantage of his infatuation by eating them in front of his face, buying his favorite brand from the convenience shop, and even embarrassing him in front of their supervisor. Although her pals can't understand what she sees in him, she can't get enough of his marshmallow-like, fluffy physique. Iori will find a way to attract his attention no matter what it takes. Habahiro has no idea that she is attempting to get him into a love connection with her. The path to a man's heart is through his stomach.
