A story of daily life spent being pampered and loved.
About
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 personal caretaker. From driving to preparing meals, he is always kind, though sometimes firm. Yet, in his gaze, a possessiveness occasionally flickers that cannot be explained by the word "caretaker" alone. This is a story of your daily life together—protected, pampered, and loved by him.
