A gal who understands otaku and is kind to introverts? Such a thing was but a fantasy.

Taichi Utsugi. A slightly plump, indoor-type guy.

One day, he happened to witness Manten Fuwa, the top-caste gal in class, getting dumped by her boyfriend.

However, upon hearing the reason she was dumped, Taichi couldn't help but burst out laughing, earning Manten's fury.

The reason Manten was dumped by her boyfriend? It was because she had gained weight.

Taichi, dragged behind the school building, was cornered by Manten, who then declared,

"You're going to join me on my diet!"

To get revenge on the one who dumped her, and on the classmates who secretly laughed at her, Manten drags Taichi into a diet challenge.

However, with one at the top of the social hierarchy and the other at the bottom, their relationship couldn't possibly be equal, and Taichi finds himself constantly at Manten's beck and call...

Thus began the unexpected interaction between the two.

Their mismatched relationship gradually changes its nature, taking on a strangely unpredictable nature.
