Sogabe and Kusuda decided to have a Christmas party in order to spend Christmas with the ones they love. They all agree to exchange presents. Kei Enomoto decides to buy Kusuda a present for Christmas but runs into him at the store. Embarrassed, they both start acting cold to each other, leading Enomoto to say harsh things to Kusuda, hurting his feelings. Enomoto tries to apologize but never gets an opportune moment to. In an unforeseen chain of events, Chikura catches a cold (and Sogabe deciding to go visit her) and Mamoru (and Ayumi) leaves to help a sick man... leaving an odd couple like Enomoto and Kusuda alone on Christmas.
