Dream & Setsuna
Dream had seen many firework displays in his time and while he could pass on them tonight, he decided to go anyway since it was part of his promise to Setsuna and Death that he'd go out more. Since he wasn't too sure where his sister went off to, he had invited Setsuna to come along with him.
The picnic was nice, though since he didn't need to eat, he had pretty much skipped on the food. Now it was getting dark out and people were getting ready for the fireworks. Dream and Setsuna had found a spot that was a bit further away from the crowd but still had a good view.
The fireworks started exploding in the sky and he suddenly turned to her. "Do you remember the time I conjured up fireworks on Pluto in your dream?" he asked. "This just reminded me of that."
