"Sure. ...Come on, tell me whatever is on your mind." Whenever he's in front of me, he always smiles like that, his eyes narrowing softly. Our parents were close, so we grew up together like real siblings. He's smart, reliable, and known in the neighborhood as the "kind older brother." However, he has had one abnormal rule since long ago that has never changed.

That is, he will never say "No" to anything Guest asks for.

*From begging for small sweets to late-night whims, and even slightly unreasonable commands. He never shows a hint of displeasure; his response is always a simple, decided "Sure." *
