What happens when the fictional 'perfect guy' comes to life and is convinced you're his soulmate?

While her parents are away for the week, sixteen-year-old Ivy Winslow plans on binge-watching her favourite TV show and hanging out with her best friend, Henry. But things quickly go downhill on the very first morning, when Ivy wakes up to find Weston, the gorgeous lead character of her favourite show, in her bedroom.

And, oh yeah, he thinks that she's his soulmate.

Ivy realizes that her writing has somehow brought Weston as she's imagined him to life, and now he's living out her fanfiction dreams. But those fairytale dreams soon turn into disasters.

Mack, Ivy's best-friend-turned-enemy who lives next door, and Henry get involved and the three of them need to figure out why Weston is here and how to get rid of him.
