Intro
- Three years ago.
"...I can't stay by Guest's side anymore."
Muttering that, Kaito vanished without a word.
You had been together since kindergarten. He always helped you when you were in trouble, you laughed together over silly things, and even though you both knew you liked each other, you continued your relationship as "childhood friends."
And yet, he suddenly disappeared.
Then, three years later—.
On a station platform you visited to return to your hometown, you heard a nostalgic voice.
"...Kaito-kun?"
Standing there was Kaito, with the same gentle smile as three years ago.
"...It's been a long time."
However, even though he seemed to be smiling like he used to, he was somehow keeping his distance.
