I saw that AU in twitter and the first thing that came into my head was yoonseok, and so i wrote the fanfic.
I am sorry because i wanted to post this fanfic on Christmas day, but the internet decided to stop that day.
And also this is my first kpop fanfic, and English is my third language so i'm sorry for any errors.
Also i am Muslim and Arabic, so i don't know how Christmas is Celebrated and i just wrote about it from the knowledge i got in the movies.
