All she wants is to break off her engagement… But the “heroine” she picked to steal her fiancé might be way too dumb!? Nicknamed the “Queen of Hearts” for her prideful demeanor, Lady Katerina, a marquis’s daughter, is troubled by her engagement to the ever-popular Crown Prince Michel. Tired of being overshadowed and emotionally cornered, she hatches a classic romantic plot: orchestrate her own broken engagement! To do so, she needs someone to “steal” Michel away from her—and she finds her candidate in the lower city: the penniless baroness Lilith Valentine. There’s just one problem… Lilith is a total weirdo. “Please call me your dog, my lady!” Is this really okay!? No—it’s not. But also… there was literally no one else. With absurd schemes and chaotic misunderstandings piling up, Katerina’s daily screams echo once more! Can she successfully destroy her engagement and win her freedom? Let the rampaging rom-com of a broke noblewoman and a noble disaster begin!
