Kim Himchan loves christmas, but his 'bah humbug' of a boyfriend, Bang Yongguk, begs to differ. He complains that it's too cold and there's no point in going out on lights and a messy tree that is only used once every year. The decorating is a hassle and what's worse - he has to do shopping. But what happens when Himchan finally snaps, leaving Yongguk locked out on Christmas Eve and Christmas Day?
