Ryoji and Miki, who hadn't even shown any signs of being in a relationship, suddenly announce their marriage! Ryoji's classmates, who used to gather at his house for drinking parties on every occasion, are surprised but congratulate the couple. "I wonder if this will be the last time we gather at Ryoji's place like this," they say, and while they're in a celebratory mood, they drink until the morning, thinking that things won't be the same as before once they have a family. And as the light begins to fall on their way home, Jun makes up his mind and heads back to Ryoji's house alone.
