Takano Masamune met Onodera Ritsu in the school library in the third grade, and has been secretly in love with him for the next three years. In my senior year, I accepted Onodera Ritsu's confession and had a brief love affair. However, due to improper expression, Onodera Ritsu thought that he had been cheated, and immediately left Takano Masamune to study abroad, because he didn't want to go to school. In the second episode of the animated version, this practice was dubbed "roundhouse kick" by Takano Masamune. According to his own explanation, it was because he was a child. When asked if he liked Onodera, he smiled to hide his shame. Later, the cartoon explained that I was thinking, "What are you talking about?" ).

Later, due to the divorce of his parents, he changed his surname to Takano. During my college years, I was once degraded because of family changes (knowing that I was not related to my father) and Onodera's unexplained disappearance. When Yokozawa Takafumi gets back on track. Later, because Yokozawa Takafumi entered the publishing industry, he moved to Marukawa Bookstore. After serving as the editor-in-chief of the editorial department of Emerald, he became the first in the publishing department of the company from the bottom editorial department within one year, and also won the president award. He has a strong ability to work, but correspondingly, Takano Masamune is merciless and even mean to people, but he is actually a type of being cold outside and hot inside.

Frivolous (only for Onodera), on the first day when Onodera Ritsu entered the editorial department of Jade (which he didn't approve at first), Takano Masamune claimed to be a model in order to let the cartoonist draw a good plot, and kissed Onodera Ritsu (in his words, it was all for work reasons).

In the second episode, he confirmed his identity, and later claimed to make him like himself again, and happened to be a neighbor of his new apartment in Onodera Ritsu. This is the plot in the animation. The cartoon character Nakano Temple lived next door to Gaoye for a year. Because of different work and schedules, they haven't seen each other for a year, and Onodera met by chance after jumping ship. See the cartoon Onodera Ritsu occasionNo. 1)

In fact, at first he was indifferent to Onodera's love for himself, because his parents were indifferent to him, which led to his distorted and indifferent character. But in front of Onodera Ritsu's sincere love, he was moved. (See Comic Takano Masamune OccasionNo. 1)

According to observation, he may be influenced by Onodera's pure feelings when she was a girl cartoon editor in high school.
