Habahiro Hige is an older guy with a basic intellect who works in an office and enjoys Tabekko Marshmallows. His days are typically spent being ridiculed by Iori Wakabayashi, a 24-year-old coworker who takes advantage of his infatuation by eating them in front of him, buying his favorite brand from the convenience shop, and even embarrassing him in front of their boss. Her pals don't understand what she sees in him, but she can't get enough of his marshmallow-like, fluffy form. Iori will find a way to attract his attention no matter what it takes.
