Inoue Kazuki loves eating delicious food.

Upon becoming a second-year high school student and finding himself in the same class as the school's most beautiful girl, Hoshino Miyao, Kazuki discovers her cooking is delicious and confesses, asking her to become a yandere and cook for him endlessly.

Miyao isn't sure if she'll become a yandere, but she says she might cook for him if he agrees to one condition.

That condition is for him to act as her boyfriend.

So, she immediately comes over to cook for him, but thanks to Kazuki's younger sister, they end up having to be more lovey-dovey than she had expected.

Since Miyao's cooking was truly delicious, Kazuki resolved to definitely turn her into a yandere so he could enjoy an endless supply of delicious meals.
