After five years apart, Callista and Elliot, who were once in love, coincidentally cross paths again at a reunion celebration. Although they were "high school sweethearts," Callista moved to the US and finished her education there, which caused them to break up. When they reconnected at the reunion celebration, their old classmates continued to make fun of them and reminisce about the wonderful and memorable times they had in high school. Callista was unaware that Elliot was her parents' business partner, but now that she is about to take over as CEO of their company, they will be working together. What if the former lovers start working together?
