Setsuna and Dream
Dream hadn't really planned on going to the party. He wasn't celebrating anything or had any other reason to go. He was going to simply stay home while his sister went out. But when Setsuna invited him, he decided to go. Mostly because he did want to keep his promise of going out more. And also because he enjoyed her company.
He suddenly appeared beside her just because he could. "Setsuna," he greeted her. "You love lovely, as always."
