It all started with that bet. Will got challenged, by the death boy himself, to make him smile or laugh and he only had 24 hours. The loser should do whatever the winner asks for. Will is determined to make Nico laugh, not to win the bet, but to be able to see his crush smiling and laughing. On the other hand, Nico is more than happy to spend a whole day with Will, but he feels like it would be impossible not to smile or laugh around him. Is Nico going to win this bet? Or is Will going to be able to make the death boy smile? Who will win? And what will they ask from the loser?
