In "Whose Hello?", players assume the role of an anxious yet witty detective in a quirky town where people mysteriously greet each other with bizarre phrases instead of simple hellos. Uncover the truth behind these strange greetings while interviewing eccentric townsfolk, collecting clues, and piecing together the town's secret history. Each choice leads to hilariously unexpected outcomes, with unexpected plot twists waiting around every corner. Engage in dialogue that changes based on your titular catchphrase, using it to charm or bewilder your way through the case. Will you solve the mystery and restore normal greetings, or will you get lost in the madness of absurdity?
