Ryūji Takasu is frustrated at trying to look his best as he enters his second year of high school. Despite his gentle personality, his eyes give him the appearance of an intimidating delinquent. He is happy to be classmates with his best friend Yūsaku Kitamura, as well as the girl he has a crush on, Minori Kushieda. However, he unexpectedly runs into “the school’s most dangerous animal of the highest risk level”—Taiga Aisaka—who just happens to be Minori’s best friend. Taiga has a negative attitude towards others and has a habit of snapping violently at people. She takes an instant dislike to Ryuji, and it turns out she is living in an apartment facing Ryuji’s house. When Ryūji discovers that Taiga has a crush on Yūsaku, and Taiga finds out about Ryūji’s affections towards Minori, they make an arrangement to help set each other up with their crushes.
Over the course of the series, Ryuji and Taiga try to set up romantic situations to help each other get to know their friends, but many of the situations backfire. Their classmates observe that they are spending a lot of time with each other, leading to rumors that they might be a couple. Although Ryuji and Taiga try to dispel the rumors, they find that they do enjoy each other’s company, with Taiga visiting Ryuji’s house to share meals, and Ryuji checking up on Taiga to get her to school, and cleaning for her. They meet Yusaku’s childhood friend Ami Kawashima, a popular teen model who transfers into their school. She appears to be friendly and is a self-proclaimed ditz, but beneath her facade is a rather mean and spoiled brat, and she quickly finds herself at odds with Taiga. In spite of this, Taiga tries to put up with her antics as Yusaku wants them to all get along, and Ami begins to grow fond of Ryuji. The series follows the lives of the five, as seen primarily through the eyes of Ryuji, with the characters growing and developing through their interactions with one another.
