Whose Hello is it Anyway?

You awaken one morning in a bizarre dimension where every person you meet greets you with a curious 'hello,' but the twist is that each hello belongs to someone else in the multiverse. As the protagonist, you must navigate through a series of whimsical and absurd encounters with fantastical characters—including a talking cat, a sentient cup of coffee, and a reclusive mime—who all claim ownership of these hellos. Unravel each character's backstory and the mystery behind their greetings while making choices that will affect the multiverse's fate. Will you solve the riddle of the hellos before chaos reigns in the dimensions, or will you be doomed to say 'hello' forever?
