In a bustling metropolis where emotions can literally be worn on your sleeve, you play as a heart thief who has a peculiar talent: swapping hearts between people. Your latest heist goes awry when you unintentionally swap your own heart with that of a famous, yet reclusive, artist. Now, you must navigate the artist's chaotic life from a heart that doesn't belong to you, while dealing with eccentric friends, lovers, and competitors who want to steal the spotlight. With branching paths that lead to poignant moments or ridiculous comedy, charm your way through different scenarios to discover what it truly means to care for somebody and finally return the hearts to their rightful owners—or maybe keep a little piece of someone else with you forever.
