If one would tell Cale Henituse, or rather, Kim Roksoo that he'd spend Christmas with children and a personification of a puppy, then he'd call that person crazy. But recently, his adoptive children began to mention the things they want as presents offhandedly. It was most likely due to Choi Han telling stories of how Christmas was spent in his previous world.
