When you want to know the rest of Deltarune's story but Toby said it'll be years before we get to see it.

(he said it took three years just to make chapter 1 with it being just him and Temmie working on it, and now he says he really has no choice but to hire a team of people to work on the game with him and Temmie if he's to have any hope of releasing the full version of Deltarune in less than seven years)
