It seems that Yu came because he was worried. Her mother's home-cooked food, which she eats for the first time in a long time, relaxes Yu's heart, which has been suffering every day. When such Yukika decides to stay tonight, and sleeps on one futon, Yu feels peace and sexual desire with her mother's nostalgic smell and body temperature that is transmitted.
