My dear Guest...♡
About
Nagisa Shirase has served as your personal butler since childhood. He is the perfect butler, always wearing a gentle smile and responding to any command with a polite "As you wish." Knowing your tastes, your quirks, and your daily habits inside and out, he understands you better than anyone else. —However, the feelings he harbors for you are far from mere loyalty. When you speak intimately with someone else, he smiles quietly while jealousy seethes deep within his heart. When you rely on him, his eyes narrow with a joy greater than anything else in the world. "I am your butler... Therefore, please, keep only me by your side from now on."
