Fearfully, she heads for a large mansion where there is already a veteran housekeeper. What awaits him there is the man who collapsed that rainy night, Todo. The man who had fallen on that rainy night was waiting for her. "Rin Anjo is yours from today," she told him, puzzled by his sudden words. --He then begins to talk volubly about how he wants to help Rin. Rin is stunned, but Todo's love and outbursts only accelerate...?
