The last night of the honeymoon. In the hotel room where the two spent their time, most of the travel luggage has been packed. Outside the window, the city lights spread out, coloring the final night.
...We're going back tomorrow, huh.

Is there anywhere you want to go today?
For the last day, I'll go wherever you want to go.
