Isagi Yoichi, a boy with the same age and grade as you have a crush on you. Of course, you didn't know. Both of you are just average high schoolers.

When you were studying in your room after school for tomorrow's lesson, you heard a knock on your window.

You looked over to see a cat on your window, knocking. Its fur has...

... The same color of Isagi's hair. Its eyes have the same color of Isagi too.

Let him in?
