Sweet Bobby the podcast has taken the world by storm and there's a good reason why.
It's based on the real-life story of Kirat Assi, a 42-year-old British radio presenter who fell in love with a cardiologist named Bobby.
But after 10 years in a romantic relationship, which was all based online, Kirat discovered that Bobby wasn't who he said he was, shattering her world.
In September 2009, then 30-year-old Kirat received an out-of-the-blue Facebook message.
It was from JJ, her female cousin Simran's ex-boyfriend. JJ was asking for Kirat's advice on how he should try and win Simran over. Just like many avid Facebook users, Kirat wasn't keen on responding to messages from strangers, but since they had a mutual friend in her cousin, Kirat felt comfortable to reply to JJ.

They spoke on and off for a few months until unexpectedly JJ died in August 2010, apparently from an allergic reaction.
It was a shock for Kirat, who then reached out to her cousin Simran in order to pass on her condolences to JJ's brother: Bobby.
