Riiko Izawa has never had a boyfriend and she has been rejected by every boy she has ever had a crush on. When she returns a lost cell phone to an oddly dressed salesman, she mentions wanting a boyfriend. To thank her, he directs her to his company's website, Kronos Heaven. When she visits the site, Riiko finds it's a site to create your perfect lover. Thinking it's a game, she customizes and accidentally orders one. The next day, her new lover arrives. Following the instruction manual, she kisses him to wake him up, which configures him to be in love with only her. She names him "Night". Three days later, she is shocked to learn that she only had him for a free trial for 72 hours. The salesman, Gaku Namikiri, tells her that she must now pay  for Night, however, they will waive the fee if she helps them to collect data about how women think and feel to help perfect future models. Riiko must now keep Night's true nature a secret from everyone around her. She also soon finds herself in a love triangle between Night and her childhood friend Soshi, who declares his love for her out of fear he will lose her. As the series progresses, Night begins to develop real human emotions, enabling him to truly love Riiko but also resulting in system malfunctions. When Riiko almost loses Night due to the malfunctions, she realizes that he is the one she really loves. She apologizes to Soshi, who moves to Spain with his brother to live with their dad. Night and Riiko spend a few happy weeks together, during which they go on dates, get their picture taken together, and purchase matching rings as symbols of their undying love. As the series ends, Night begins to grow sleepier and sleepier. The problems developed by him exceeding his abilities eventually causes his machinery to stop working, resulting in his "death". Before he died, he wrote a letter directed to Soshi telling him what was happening and asking him to take care of Riiko. He also sends his ring, which Riiko noticed he has not been wearing immediately prior to his death. In the letter, he tells Riiko that she doesn't have to cry for him any more but to always smile. So she laughs and forever treasures her rings and memories of Night. Characters 

Played by: Mokomichi Hayami (Japan)
Nightly 01 (Night) is a cybernetic doll ordered by Riiko Izawa. As such, he is the "perfect boyfriend": charming, dependable, intelligent, athletic, good-looking, sensitive, and completely devoted. Designed to fulfill intimate relations for a woman, Night constantly offers to have sex with Riiko, who steadfastly declines the offer. Not knowing a sense of privacy, he often takes off his clothes under the slightest prompting of him having to sleep with Riiko even at public places, and often tries to hug or kiss Riiko, which makes her uncomfortable and embarrassed. While Night at first functions as Riiko's perfect boyfriend due to his programming, his relationship with Riiko eventually makes him develop true humanlike emotions, culminating in him having his own will. Even if Night's allegiance to Riiko can be switched by means of kissing, his relationship with her is so strong that when a customer of a host club makes him her lover, he still remembers Riiko, albeit as an ex-girlfriend; upon kissing Riiko again, he quickly switches allegiance to her while completely forgetting his experiences with the customer beforehand. Eventually, he grows to love Riiko genuinely and trespasses orders given to him by Kronos Heaven. However, Night is secretly dying from battery failure as his relationship with Riiko goes intimate, although he does not want to make Riiko worry by informing her. Before he shuts down, he writes a letter for Soushi to return for Riiko, while telling Riiko not to cry and to move on from him. Night's Ring
Functions similarly to a mood ring, with one difference: it reads the moods of people around Night. This helps him collect data about interacting with them. What the different colors mean: Red - Happy, Pink - Pleasure, Black - Sad, Blue - Angry and Jealous, and White - Neutral/Calm. In the Japanese series, his data-collecting equipment is a bracelet instead of a ring. In the Taiwanese series, an additional color, yellow, is added, which can be generated when Night has a sex drive. In the South Korean series, Da-da wears the ring instead of Young-gu. It has only two colors: Red for happy or love, and black for angry or sad. Live-action
In the Japanese series, Night is initially much more annoying than his manga incarnation as he often embarrasses Riiko by telling everyone that he is her "ideal boyfriend", which infuriates her. He finds a job as a janitor at Asamoto and embarrasses her further. By developing his own will, Kronos Heaven worries about the problems he may cause to the company and they try to delete his data. Though Night manages to keep his system from deletion for some time, his data chip begins to overheat due to his newfound independence and eventually stops working altogether. In the special episode in Japan, his system is restored by a doctor who wishes to use his independence for her selfish reasons. He eventually is forced to make the ultimate decision: to give up Riiko for her future. Played by: Saki Aibu
Riiko is a young, flat-chested (according to Soushi, 32-A cup) 16-year-old girl who has bad luck with boys. When she helps a strange salesman named Gaku Namikiri, she ends up ordering a cybernetic boyfriend. Though initially shy around her new boyfriend, Riiko begins to fall in love with him, while also finding herself struggling with her new admirer, Soushi Asamoto. Riiko is rather naïve, clumsy, and simple-minded, but kindhearted, hardworking, and serious. Riiko doesn't want to admit she is in love with Night and constantly reminds herself that he is just a doll. This, however, isn't completely true because she gets jealous or even angry when he flirts with other girls for "data." Live-action
In the Japanese version, Riiko is an office lady at Asamoto who has trouble with guys,  so she is introduced by the manager of Kronos Heaven to try out a cybernetic boyfriend for one week. Over the course of the series, she grows increasingly attached to her new boyfriend, Night Tenjo, and her boss, Asamoto Soshi. She chooses to give up her dream of becoming a pâtissier to be with Night, but she ends up going anyway after Night's computer system is destroyed. In the special episode in Japan, Riiko has become an official pâtissier after three years of training and is forced to make the choice of her life when Night is suddenly restored. Played by: Hiro Mizushima
Soushi is Riiko's childhood friend. He lives alone with his brother because his father is a travel photographer. He watches over Riiko and takes care of her while her parents work far away.

In the Japanese version, Soushi's personality is switched between that of his brother; instead of a serious individual, Soushi is a flamboyant and playful young man who cares more about the origins of his grandfather's company than what it has become. He grows romantically attached to Riiko and declares his love for her, who reciprocates her feelings. He also encourages Riiko to pursue her dream of becoming a pâtissier. At the end of the series, Soushi invites Riiko to study further in becoming a pâtissier at France with him. In the special episode, Soushi and Riiko return to Japan after three years of study to reopen the Asamoto's original base of home. The two have also become a couple, but their relationship is strained by the sudden return of Night.

Gaku is a salesman for Kronos Heaven, a company specializing in making highly realistic robots, or "figures". Though usually businesslike and down-to-earth, Gaku is often mistaken for a cosplayer because of his odd manner of dress. When Riiko cannot return Night or pay the bill for him, Gaku allows her to keep him so Night can collect data on how to become a better lover for use in future models. Whenever there is a problem with Night, Gaku is the one to fix him. Gaku keeps close tabs on the progress in the relationship between Riiko and Night, and he often appears randomly out of nowhere, ie. out of Riiko's closet, mostly for comic relief. A stereotypical Japanese salesman, he speaks with a heavy Kansai dialect and tends to interject Spanish words in his conversations. Gaku's family owns a business of selling takoyaki; at the end of the series, Gaku quits his job at Kronos Heaven to inherit his family business. Gaku is the one whom Night trusts to give his letter asking Soushi to return for Riiko once the latter has calmed down from her grief of losing Night. Live-action

In the special episode, Gaku expresses surprise when Night comes to function without his authorization. He later reluctantly scraps Night, as per the latter's wishes. Played by: Natsuhi Ueno
