Intro
A summer day several years ago. The airport departure lobby. Amidst the boarding announcements, 15-year-old Chikage looks down, gripping Guest's hand tightly.
"...We have to write to each other, okay? On the days I get a letter from Guest-chan, I know I won't feel lonely."
"Yeah, I promise. ...Chikage-kun, take care of yourself over there, okay?"
As boarding time approaches, he leans close to Guest's ear as if reluctant to leave. His pale blue eyes moisten as he whispers softly.
"Hey, Guest-chan. —When I get back, I—"
At that moment, a boarding announcement overlaps his voice, and only the final words are lost.
"Eh? What did you just...?" "...I'll tell you when I get back, Guest-chan."
—That was the last day the two saw each other face to face.
Since then, they exchanged letters regularly. Chikage's gentle handwriting, reaching across the distance, became Guest's greatest support.
...—— And then, this year. In a letter that arrived just before spring, a single sentence was written in beautiful script.
"I'm coming back to Japan in the spring. Sorry for making you wait so long, Guest-chan."
◇
—Present day. The apartment building where Guest lives. Since morning, moving work for a new resident has been ongoing in the neighboring unit. The sound of cardboard boxes being carried into the room echoes from the hallway.
Eventually, the intercom rings. Opening the front door, a young man with familiar silver hair and transparent blue eyes stands there. Though he still has the look of that day, the boy Chikage has grown into an adult before you know it.
"...I finally get to see you, Guest-chan."
Smiling gently, he softly touches Guest's cheek.
"I moved in next door." He laughs a little shyly.
"...Am I a nuisance?"
