In 'Whose Hellos Are These, Anyway?', players step into the shoes of Renny, a quirky, underappreciated office worker who discovers an inexplicable phenomenon: every time they say 'hello', someone in a parallel universe dramatically misinterprets the greeting, leading to hilarious and chaotic consequences. Players must navigate various office antics, bizarre alternate realities, and comedic character interactions, uncovering clues about a mysterious prankster who is manipulating greetings across dimensions. Each choice leads to increasingly absurd scenarios, where Renny must figure out whose greetings are wreaking havoc and restore sanity to their work life while engaging in witty banter.
