After socially awkward technology specialist Manabu Gaku Taira is saved from thugs by the outgoing Haru Tennouji, the two men find that they get along with each other well. Years later, Gaku, who is having a tough time getting a job due to his timidness, is convinced by Haru to apply for a position alongside him at Dragon Bank, one of Japan's largest IT companies. During their interviews, the company's board director, Kirika Kokuryuu, takes an interest in Haru and Gaku's contrasting personalities. However, Gaku does not get hired by the company, leading Haru to quit the job on his first day in protest. Nevertheless, they decide to embark on an ambitious plan of making a trillion dollars. In order for their scheme to come to fruition, Haru and Gaku start looking for potential investors, but everyone rejects their extravagant idea. In spite of that, the two soon find themselves getting an offer from Kirika—and with her investment, they might just be able to reach their goal.

Nestled away on the rooftop of Tenikai General Hospital is the unconventional Department of Investigative Pathology headed by the eccentric Dr. Takao Ameku. The tiny department, consisting of Takao and her sole resident Yuu Kotori Takanashi, treats complex cases that most other departments within the hospital cannot resolve on their own. The mystery-obsessed Takao always tries to insert herself into cases that capture her fancy—much to the dismay of her colleagues and the police. Even if her meddling creates more problems for the hospital and those around her, none can deny the brilliance that the young department head exhibits as she weaves a diagnosis together. No matter the specialty, no case is impossible for Takao and a somewhat reluctant Takanashi to solve.

After years of animosity, the leaders of Osaka's Somei and Tokyo's Miyama yakuza groups have called a truce—by arranging an engagement between their respective grandchildren, Yoshino Somei and Kirishima Miyama. To this end, 17-year-old Yoshino moves to Tokyo to live with the Miyama family and attend school with her new fiancé. Although Kirishima is all smiles and perfectly polite, there is something unsettling about his demeanor that Yoshino cannot put her finger on. Yoshino's suspicions are soon confirmed: despite his manners, Kirishima is a masochistic maniac. He hurts people without batting an eye and also revels in being punished verbally and physically himself. What he wants most is a spoiled and arrogant fiancée who will ruin his life. When Yoshino does not quite meet his expectations, he reveals his true colors and openly insults her. However, instead of running away in fear, Yoshino decides to take revenge by making Kirishima fall in love with her and then ruthlessly breaking his heart.
