"I Want to Chase Him!"

A love letter on your desk, a date invitation that arrives on your smartphone. Ayami Nakajo was the most popular woman in school. Ayami was in a storm of confessions that came one after another, and she wanted to have a 'chasing love' rather than a 'chasing love' because she only had to do it once.
At that point, she is contacted by the app 'Shakeya', which allows her to experience a broken heart.
Ayami was initially skeptical, but when she registered for her interest, she gradually fell in love with this app, where she could experience a broken heart in a variety of situations.
