Whose Hello Is It Anyway?

In a bustling metropolis where greetings are currency and politeness can unlock secrets, you play as a nameless protagonist who wakes up in a library filled with strange books that can bend reality. Each book leads to unique characters — from a grumpy librarian with a secret past to a time-traveling barista who forgot everyone's name. To progress, you must master the art of greeting, conversing with each character and uncovering their fantastical stories while unraveling a conspiracy that threatens the very fabric of friendliness in the city. Will you gather enough charm and wit to restore social order? Or will you become a footnote in this wild narrative?
