Whose Hellos Are These, Anyway?

In a bustling metropolis, greetings become mysterious tokens of connection when a series of cryptic messages appear across the city, signed only with puzzling 'hellos.' Players step into the shoes of a witty and somewhat cynical urban locksmith, who discovers that each 'hello' is not just a greeting but a clue leading to dramatic events unfolding in the lives of ordinary citizens. As players navigate through branching storylines, they will make critical decisions that alter the course of relationships, confront elusive figures from their past, and unravel a conspiracy that ties strangers together through unexpected encounters. Can you decipher the meanings behind these hellos before the clock runs out?
