In 'Whose Hello?', players step into the shoes of Alex, a quirky, down-on-their-luck private investigator who specializes in retrieving lost greetings. In a world where social etiquette is both revered and comically absurd, Alex navigates the eccentric lives of their clients, each with a bizarre story tied to a missed hello. As players solve puzzles, uncover secrets, and forge unexpected alliances, they must interact with colorful characters who embody society's strangest quirks. Each interaction can lead to wildly differing paths and endings that depend on how players choose to greet or neglect their encounters. The clock is ticking as a mysterious figure begins to erase greetings from the world completely, and it’s up to Alex to solve the mystery before every ‘hello’ fades away forever.
