Kim Mingyu does not know what is waiting for him... Jeon Wonwoo does not either.

It's funny, almost. Nobody would ever suspect what's behind Mingyu's smile; his tender gaze hides more than it is shown.

Who would ever think it was the fault of an 18-year-old boy... other than Jeon Wonwoo?

And who is Wonwoo? I think that's what everyone wants to know.

But you shouldn't, really.

We all have demons inside us that we need to kill.
