Kai was reading his favourite novel's final chapters that some sends him secretly but one day chapters stopped coming instead a Message came.

[what would you do if you were there ?]

[where ?] Kai asked.

[inside the novel...]

and to his wish everything changed and he found himself inside the same novel.
