In this story, we learn about a young couple: Alicia and Jordan. Based on the description that the narrator gives us, Alicia and Jordan are newlyweds. However, Jordan is a passive, quiet man who does not display affection easily. On the other hand, Alicia is more open and loving, and this mismatch seems to cause her some suffering. The neglect and solitude she feels cause her to fall sick, and it is only during her illness that Jordan realizes the love that he has for her.
