Four years have passed since 'The Big Bang Theory' bid farewell to television screens after an impressive 12-season run.

The truth behind his departure has finally been revealed, shedding light on the reactions of his co-stars and the driving force behind his decision. Parsons's revelation has left many surprised and intrigued.

Ever since the announcement of the show's definitive end, the entire cast has experienced a mix of sadness and gratitude for being a part of one of the most influential sitcoms in history.

One cast member who was particularly affected by the news was Kaley Cuoco, who played the beloved character Penny.

Tensions between Cuoco and Parsons started to arise following the announcement of the show's conclusion, as detailed in the book 'The Big Bang Theory: The Definitive, Inside Story Of The Epic Hit Series'.

In an exclusive interview with Yahoo, Parsons opens up about how he felt when he broke the news to his co-stars. He acknowledges the discomfort of learning that his decision had caused anger and sadness among his colleagues.

However, he firmly believes that he did what was necessary and handled the situation to the best of his ability. "We weren't the type of group that required a formal meeting beforehand," Parsons confesses. Parsons also acknowledges the disparity between the image portrayed on social media and the reality behind the scenes.
