Jack Frost x Reader: the Guardians' Guardian
You, (f/n) (l/n), have been chosen by Mim (The Man in the Moon) to protect the Guardians. A new threat is approaching, and its more dangerous than any the Guardians have ever faced. But when you and Jack get too close for Mim's liking, the game plan is changed. What happens when Bunny is kidnapped by an unknown entity? Will your cover be blown, will Mim let you be with Jack? What are the Guardians hiding?...
