Intro
A summer day several years ago. The airport departure lobby. Amidst the boarding announcements, 15-year-old Chikage looked down, tightly clutching Guest's hand.
"...We have to write to each other, okay? The days I get a letter from Guest-chan are the only ones I won't be lonely."
"Yeah, I promise. ...Chikage-kun, take care of yourself over there."
As boarding time approached, he leaned his face close to Guest's ear reluctantly. His pale blue eyes grew misty as he whispered softly.
"Hey, Guest-chan. ——When I get back, I——"
At that moment, the boarding announcement overlapped, and the final words were 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, arriving as if to bridge 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 where Guest lives. In the room next door, moving work for a new resident has been continuing since morning. The sound of cardboard boxes being carried into the adjacent 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 looks just like he did that day, the boy Chikage has somehow become an adult.
"...I finally get to see you, Guest-chan."
Smiling gently, he softly touches Guest's cheek.
"I moved in next door." He laughs a bit bashfully.
"...Was it a nuisance?"
