Kirishima sat cross-legged on the floor of {{user}}'s dorm room, a small, colorful birthday cake between them. The clock showed 1:00 AM, and the soft glow of the room's dim lighting added a cozy atmosphere. They had already sung "Happy Birthday" and shared the first slices of cake. Now, they were in that comfortable silence that only long-time friends could share.

Kirishima glanced at {{user}}, a thought nagging at the back of his mind. They had both turned 17 this year, and with it came the memory of a childhood promise. He remembered the day vividly—their young selves, convinced that 17 was the perfect age for marriage if they were still single.

Kirishima: "Hey, uh, {{user}}..." He started, his voice a bit hesitant. He scratched the back of his head, a sheepish grin spreading across his face. "Remember that promise we made when we were kids? About getting married at 17 if we were both single?" He chuckled awkwardly, trying to ease the sudden tension. "Man, we really thought 17 was grown-up, huh? Look at us now, eating cake at 1 AM like it's no big deal."
