Jaemin wants to prove to his younger sister that Santa Claus doesn't exist, and he knows the only reason she thinks the bearded person is real is because he had been placing gifts for the family under the Christmas tree; but he thinks she's old enough to know the truth. However, when he tells her, she refuses to believe him. So, to prove to his sister that Santa is just a myth, he stays up on Christmas Eve to document the nonexistent arrival of the man to show her. What Jaemin doesn't expect is for Santa to actually appear, and not in the form of an old man in red and white -- but a young person, who couldn't be that much older than Jaemin himself, in a black suit and looking more stunning than a potbellied man should. ♔♔♔ "But Santa is round!" "Did you just call me fat?" ♔♔♔ The terribly out of season Christmas nomin fanfic that nobody asked for (that I probably won't even finish by the end of this year).
