In 'Whose Hello?', players take on the role of a bumbling private investigator named Max Mixup, who has a knack for mixing up names and faces. One day, while sitting in a crowded diner, Max overhears a bizarre conversation about a stolen 'Hello' - a magical phrase that grants the speaker immense charisma and confidence. In a race against a quirky band of rival detectives, players must gather clues, interview eccentric characters, and piece together the bizarre mystery surrounding the missing 'Hello'. Will you solve the case before your competition does, or will you be left with just a whisper?
