Love Island 2023 viewers realised something about Sanam Harrinanan and Kai Fagan 's win on Monday night, just as they shared how happy they were with the result.
The couple's victory marked a show first for the dating series, with many commenting that it was "history making".
Sanam became the first ever Casa Amor bombshell to win the show, as she and Kai stormed to victory during the live finale.
Viewers were happy that the couple had won, and had hoped they would be the winners out of the four remaining couples.
Tanya Manhenga and Shaq Muhammad, Lana Jenkins and Ron Hall, Tom Clare and Samie Elishi, and Sanam and Kai were this series' finalists.
As host Maya Jama announced the winners, viewers rejoiced on Twitter and said the right couple won.
But some fans were quick to realise the win marked a series first for the show, despite it having had nine series.
While Casa Amor was introduced to the show in series three back in 2017 the series has never seen a Casa Amor bombshell win the show.
While bombshells and late arrivals have won the series on a few occasions, no one from the famous Casa arrivals has been as successful.
Sanam changed that on Monday night, as she and Kai won the show and the £50,000 prize money - making her the first Casa bombshell to do so.
Taking to Twitter, many fans noticed this show first and share their surprise that it hadn't happened before.
One viewer tweeted: "This is the first time we’ve ever had a Casa winner," as another said: "Is this the first time a casa amor person has won?"
A third viewer added: "Glad that Kai and Sunam won... is this the first time a person from Casa Amor has won?"
Meanwhile, other viewers were just happy to see them win after they beat all the other couples, with Ron and Lana coming second place.
One viewer said on Twitter: "Think this is the first time the vote wasn’t rigged and fan favourites actually won."
Another fan said: "Never been so happy with a love island result #loveisland they deserve it so much."
A third viewer commented about the result: "After all the anger from this season… I’m very happy with the results," while a fourth fan said: "I'm so happy with the results."
Love Island airs every night at 9pm on ITV2 and ITVX.
