Kaede enjoys a lot being with her friends. But when Christmas comes up, all the singles feel a certain pressure. And this pressure also reaches her, especially as her job is to write good slogans to sell Christmas cards used to convey love. Sadly, because she is not in love, her work performance also suffers.
