You are an idol in a famous girls group. Around Christmas time, your agency decided to give you some time off to rest after a long promotion for your album. Your girls and you are really good friends with the BTS members, and because you all have never experienced it, you all decided to go on holidays together for Christmas in a log cabin high in the snowy mountains. You were just as excited as all of your friends for these holidays, but no one could have foreseen what happened on this Christmas.
