The Story Events are replayable events that allow you to get special items in Merge Mansion. Each has their own ways of being played to win the items you will need to get those special items.
The Story Events are now sequential so that the first one that you will encounter is the Ignatius Event, followed by Lindsay's New York Story Event and then the Casey & Skatie Event.
After completing the ultimate goal of the Story Events (Casey & Skatie, Lindsay's New York Story, Ignatius Boulton), the event items on your Garage Board will disappear automatically and leave a coin in each items place. Additionally, once you have completed a Story Event, it will no longer be available to play.
