The two of them go to the train station to catch the train to Tokyo, where they'll spend the night. They're bummed that they're not going to be able to spend as much time together as they'd like, since they've been planning to go on a car trip together, but they agree to go anyway. The two decide to buy some souvenirs for everyone, since it's so rare to see them at this time of the year. They also decide to stay overnight with their parents, who are visiting an aquarium.
