In a world where every person you meet greets you with a cryptic 'hello' tied to their own secret stories, you play as Alex, a beleaguered private investigator who has stumbled upon a bizarre conspiracy involving strangers whose greetings trigger memories of unsolved crimes. As Alex delves deeper, each character’s unique ‘hello’ opens up flashbacks that reveal hidden truths, leading to shocking realizations about their pasts and the connections they share. In a race against time, you must solve puzzles, piece together fragments of memory, and navigate a web of intrigue where nothing is as it seems. Each choice you make alters the course of the story and the fates of your newfound acquaintances.
