One day, while Gakuto Suou, a gruff but culinary-loving boy, is working part-time at a ramen shop, Shizuku Kushina—a beautiful, popular gal at school—enters, completely soaked.

She's in this state because she witnessed her boyfriend, Takashi Hachimachi, cheating. His accidental discovery of this fact sparks the beginning of their interaction.

He eats mega-portion dishes with Shizuku, who is secretly a big eater, treats her to his homemade mega-portion creations, and even brings her specially-made extra-large bentos.

Initially, he got involved to comfort the heartbroken Shizuku, but watching her eat so happily, his feelings gradually began to change.

This is a story about a mega-portion cooking boy and a hungry gal, who, through making and eating copious amounts of food, slowly begin to fall for each other.
