Raku Ichijo, the son of a yakuza boss, prefers to just live a normal high school life. On the way to school he is kneed in the face by a girl, but gets tended by Kosaki Onodera, a sweet classmate that he has a crush on since middle school. The teacher announces a new transfer student, Chitoge Kirisaki, who happens to be the girl that crashed into Raku, and they start arguing. Raku realizes he has lost his locket that contains the memories of his first love, because of the collision, and asks Chitoge to help look for it. After several days their relationship gets worse that Raku tells Chitoge to stop looking. Chitoge eventually finds the locket. Afterwards, Raku's father tells Raku that he is to pretend being in a dating relationship with a girl from a rival gang in order for their gangs to make peace, but to Raku's chagrin, the girl turns out to be Chitoge.

In order to settle the feud between their families' gangs, Raku and Chitoge act lovey-dovey towards each other. The next day, Chitoge and Raku go on a date, which is heavily supervised by the gangs, but they drive each other nuts on typical activities. At a park, Chitoge heads to a restroom where she overhears her gang acting suspicious over the relationship. Raku wishes he were on a date with Kosaki instead when she suddenly appears. Chitoge returns and tells Kosaki that she and Raku are a couple.
