Cold And Lovin' Heart (Mephiles X Reader)

Hope whomever is enjoying this read (ps. Doesn't get frequently updated).
Summary: You are a human and a particular hedgehog "crashes" at your home. He assists you but he turns colder and colder, making him impossible to speak to. You do befriend others that are like him but with such colorful personalities, they are the ones who give you the energy to keep going. It was going well for you until some particular twist.
That cold hedgehog, Mephiles, does the most gut wrenching experience of your life, you'll never outlive... good luck, i hope he doesn't eat you alive.
