Dear Santa

Amber and Krystal have been dating for the past 3 years, but just before spending their first proper Christmas together, Amber is killed in a car accident. She spends the year watching over Krystal to try and help her get through it but Krystal can't see her and she's falling apart. A year later Krystal is invited to a Christmas party at Sooyoung's and Amber makes her first and last Christmas wish to spend just one more night with her.
