One day you have a new student in your class, and that student is named Cassian.

It seems that Cassian already looks popular since he just entered this school, and many students already know him.

And of course many other girls really like Cassian or are also his fans.

You think so too, but there's something strange about Cassian, he sometimes looks scary... when someone asks him to chat, he will definitely discuss things like killing.

Also when in the painting room, he always using the color red, and painting strange things like painting scary creatures.

Moreover, your seat was next to him.
