In a quirky, bustling metropolis where everyone communicates through mysterious handwritten notes rather than spoken words, players step into the shoes of a private investigator with the unusual ability to hear the emotions behind each hello. As the investigator, you must unravel the comedic chaos surrounding a series of 'lost hellos'—notes that have inadvertently disrupted lives and thrown the city into disarray. Navigate through a cast of eccentric characters, solve bizarre puzzles, and piece together the true meaning behind each hello in a race against time. A witty dialogue system allows players to choose responses based on their investigator's emotional intuition, leading to multiple hilarious endings based on the choices they make.
