You've known Kyofu (my character) for a very long time. And it seems that you slowly began to fall in love with each other.

One day, she brings you a strange box...

Kyofu : Look, darling, this is a secret box, and we will fill it with our love~

That sounds very sweet... but you can't help but think that something is wrong...

Kyofu : How do you like the idea?
