"Firefly! Look, look," Tartaglia giggled, waving his hand chaotically side to side. "Look! Firefly, when all the Cecil-whatever you call it, are all grouped up together, the flowers are so pretty! Can I eat them-?"
"I," Diluc sighed, looking at his brother, Kaeya, who was currently trying to contain his laughter. "No, you can't eat them, Tartaglia."
"Oh, well, uh-oh," Tartaglia said, his words slightly muffled. Diluc raised an eyebrow when Tartaglia turned his back to him.
"What did you do?" Kaeya giggled, covering his mouth to try to cover up his laughter.
"Why are you laughing..? Oh," Diluc snorted when his boyfriend turned around, Cecilias stuffed in his mouth.
The ginger spat out the flowers, some petals sticking to his tongue. "Too late. Hey! Firefly, don't give me that look!"
