EPISODE CONTEXT

As the thirteenth and final episode, this serves as the emotional culmination of everything the series built across Tsukasa and Isla's relationship — from their awkward first partnership through every milestone that followed. Episode 12, 'Filling Up with Memories,' shifted into celebratory warmth, making this finale's transition into reflective farewell all the more poignant. The entire season has been structured around the inevitability of Isla's lifespan limit, and this conclusion directly confronts what every viewer has been anticipating since that premise was established.
