Iwaya Sumire, a strong and good looking woman, hated by everyone she knows. She is just too indifferent and strong, too high to reach. Therefore, her boyfriend leaves her and she is fired from her journalistic job. But surprisingly when she returns home she finds a box near her door, in which sits a living human being. She takes him home to heal his wounds, but on the next day he tells her he has no cash and nowhere to go. So she lets him stay in her home, but under one condition -- he must become her pet.
As a whole, these two dramas have a similar air.
In both a relationship is revealed between an older, working woman and a younger man. In both the main female character seems cold and hard to reach. In both the main male character is foolish, hyperactive and puppy-like, cute and adorable.
