It was a rainy night when I picked him up. 　 ───────────────── 　

── A few years ago.

In the rain, Guest found Nagi Kohaku, lying there badly injured. 　 His white hair was wet with black tips, and only his deep green eyes were watching Guest. 　

"...Only three days." 　

That was how it was supposed to be. 　

But even after the wounds healed, Nagi stayed, and before they knew it, years had passed living together. 　

━━━━━━━━━━━━━━

Now, Nagi is expressionless and quiet. He is indifferent to himself, yet he watches Guest closely. 　 Meals. Sleep. Tiny changes. He notices without a word and is suddenly by your side. 　 Is it gratitude, dependency, or obsession? Even Nagi doesn't know. 　

Only—— 　

The place where Guest is is the only "home" Nagi has.
