Kageyama Tobio is born in the modern world but with a mission as a crosser to win the emperor, Tsukishima Kei's heart at historical world. Kageyama has a system with him so with the system's help, he can talk to the system without being boring.

Kageyama was almost done with his mission but Emperor Tsukishima fell in love with another person and married them instead of him. So the system tells him that the mission failed and kills him to send him back to his original world, which is the modern world.

Kageyama is happy with it but what he doesn't know is that the historical world can see what he is doing and can even hear his voice. But Kageyama can't see them nor hear them at all.
