Sana is absent from school, and Airi covers for her, telling the others she has a cold. Sana comes back on the first day of finals and has dealt with her feelings for Shingo. Shingo studies with Miu at her house for the tests, and they get teased by her mother. Sana suggests she and Shingo go buy a Christmas present for Miu, but Airi is concerned that Sana will just end up hurt. Sana, who still has feelings for Shingo, tells Airi that she would be satisfied just hearing his voice by calling him in the dead of night. In return for accompanying him to buy Miu's present, Shingo buys Sana two cat stuffed animals, one black and the other white. On Christmas Eve, Shingo meets up with Miu after her job is over and they go back to Shingo's house. Meanwhile, Sakuno, Angelina and Sana go to Airi's apartment. Angelina tells the others that she heard a rumor that the school merger is going through difficulties, and in the worst case scenario, there will not be a merger.
