As Charlie navigates through intertwining story arcs across time, they must solve puzzles, navigate emotional dilemmas, and piece together a mystery that threatens the very existence of their friendships. Choices matter: each interaction affects future timelines and relationships, leading to multiple endings that reflect the consequences of your decisions. Can you keep your friendships intact while uncovering the truth about 'Whose Hello' really initiates chaos in time?
