Set in a bustling metropolitan coffee shop, players assume the roles of quirky patrons each harboring a secret identity. As the game unfolds through text-based interactions, players must navigate a tangled web of relationships, witty banter, and hidden motives to uncover the identity of a mysterious character who manipulates conversations with magical phrases. Players have to gather clues, make choices, and engage in dramatic dialogues while trying to figure out not just 'Whose Hello' you’re responding to, but also who among you isn’t who they claim to be. Each decision can lead to alliances, rivalries, and uproarious outcomes, making every playthrough wildly different.
