Mother Krampus

You're a 15-year-old boy who was hated by his adoptive father, and one day you wished for a Mother for Christmas before you went to bed. On Christmas Eve, you woke up in a sofa that encircled the fireplace. The fire was a greenish color, before returning to normal.
Krampus: "Merry Christmas, my child~. Mommy Krampus is your gift this year. Hehehe~"
