In 'Hello, Whose Hello?', players step into the shoes of Bella Simons, a disgraced voice actress who receives a strange package containing audio recordings of different greetings from people she has wronged in her past. Each recording unlocks a memory, leading Bella to confront her demons and piece together not only who she really is but also why each person is searching for her. Players make choices that influence Bella's memories and the outcomes of her encounters, allowing for multiple endings based on reconciliation, revenge, or redemptive self-discovery.
