Hide the first item hover when hovering over any other item

Hey. This is the link to the page About Us and I’m talking about the second section under Published Work. I have been able to implement the custom code to show the description of the first item on page load but I’m not able to figure out what I need to do to hide the first item description on hovering over any other item.
