Married at First Sight Australia's Ryan Gallagher, has shared a heartbreaking post to his 184k followers on Instagram.
The 30-year-old, who has found success as a comedian since appearing on MAFS, posted a gorgeous letter from a fan named Josh - but it was the timing of the letter that will break your heart.
"Dear Ryan, My name is Josh. I am very excited that you are doing a show for me," Josh wrote. "My mum and me and my friend Sarah watched you on the married show. It was very funny when you ate the oisters [sic]. It made me laugh a lot.
"I hope won day you find a very nice girlfriend who loves you as much as I love trucks [sic]. Thank you for doing my show. From Josh."
While this may be the most adorable fan letter ever written, it's meaning has been especially poignant for Ryan, as this special little boy passed away before he could meet the comedian and give him the letter in person.
"I had to share this," Ryan wrote about the letter.
"Next year I was doing comedy at this little guys fundraiser for cystic fibrosis, [and] he wrote this letter to give to me on the day, sadly Josh passed away recently and his mum showed me this today, I've never felt that way reading anything in my life. [sic]
"RIP little man, I also hope I find a girl and get that same feeling you get from trucks!"
Ryan was paired with Davina Rankin on the show, but their relationship soon ended after Ryan discovered that Davina had begun an affair with fellow contestant Dean Wells on the show.
Ryan told Now to Love at the ARIAS that "he was done with all that MAFS stuff" now.
Sending our deepest condolences to Josh's family during this time.
