In 'Whose Hello?', you play as a quirky, down-on-their-luck private investigator who stumbles upon a peculiar case: someone is mysteriously saying 'hello' to people across the city, causing both confusion and chaos. As you navigate through a bustling city filled with colorful characters and unexpected twists, you'll need to piece together who is behind the strange greetings. Engage in witty dialogues, solve brain-teasing riddles, and choose your responses wisely, as relationships can help—or hinder—your investigation.
