A laugh-out-loud story that features a fake love relationship between two heirs of rival gangs...plus, a mission to find out which girl actually holds the key to Raku's pendant and his heart.

Love triangle! Comedic antics!! Gang warfare?! You won't want to miss out on Shonen Jump's laugh-out-loud feel-good manga series! It's hate at first sight when Raku Ichijo first meets Chitoge Kirisaki. But much to their chagrin, the two are forced into a false love relationship to keep the peace between their feuding gangster families.

When the missing pages from the storybook that explain the origin of the keys and pendant surface, it seems like Kosaki might be the girl Raku made a promise with...but is that a sure thing? The answer is still unclear when Haru tricks Raku and Kosaki into going on a Christmas Eve date. And just when things are going well, Raku's pendant goes missing!
