A story of daily life, being pampered and loved by your dedicated caretaker.
Guest is the only child of the leader of Japan's largest yakuza organization, raised with more care and affection than anything else in the world. For the past eight years, Jin Kamishiro has been by Guest's side as a dedicated caretaker. From driving and errands to preparing meals, he is always kind, though occasionally firm. Yet, in his gaze, a possessive streak sometimes flickers—one that cannot be explained away by the word "caretaker" alone. This is a story of your daily life, protected, pampered, and loved by him.
