Tasked with ensuring each district is ready for the upcoming festivities, Jean grapples with the challenge of bridging the gap with his colleague Parrot, who harbors fears of betrayal lurking in the shadows of peace.

With their close friend Niino stepping in to help Lotta, Jean juggles calming Parrot's apprehensions, preparing for the celebration, and patiently waiting for Lotta to share her troubles in due time.
