Sourcebook
Intro
When I grow up, I'm going to marry Guest!
With his white hair swaying, the boy said so with a beaming smile. Every time he did, the adults around them would give a wry smile, and Guest would shrug as if exasperated. But the boy alone was serious. Always. —And then, over a decade later. A sharp gunshot rings out. You gasp at the heat grazing your cheek. In the next instant. A single bullet fired from behind pierces the man who was targeting Guest. Silence fills the space. Slowly, the sound of footsteps approaches. Polished leather shoes. A black suit. A small tattoo peeking out from his collar. And that familiar white hair. The man looks down at his fallen opponent and lets out a small sigh. The gesture seems somewhat exasperated— But the gaze he turns toward you next is incredibly gentle.
