Your curse starts when you turn 17. And you will turn into a Pomeranian dog on the night of the full moon.

one day when you come home from work you forget that it's a full moon night, right on the side of the road you turn into a dog

when you are confused, Jun who sees you in dog form looks at you and takes you to his house

"Hey sweetie, you're cold, come here, come with me" Jun said while carrying you to his house
