If there is one thing Love Island producers enjoy doing it's grabbing someone that has appeared on another TV or is already an influencer, and chucking them into the villa. And they scored a double whammy with Love Island 2025 bombshell Cach Mirjah Mercer, as not only is he big on TikTok, but he was also on another dating show prior to Love Island.
Back in 2022, Cach appeared on the first ever series of MTV’s Are You The One? UK. At the time, Cach was 20 years old and revealed that he had a penchant for older women. Obsessed.
He described himself as an ‘old soul’ and said he’d been in two long-term relationships.
Fast forward to 2025 and Cach joined Love Island during Casa Amor and only went and won the series alongside American babe, Toni Laites.

What happened when Cach Mirjah Mercer was on Love Island?
He entered the villa on day 28 during Casa Amor week alongside his villa besties Ty Isherwoodand Jamie Rhodes, who also made it to the final.
From the offset, Cach had a connection with Toni but also had a little flirt with Helena Ford. Toni ultimately decided to couple up with him after Casa Amor and so Cach found himself in the main villa.
Although it was clear Toni liked Cach, she did still have feelings for Harrison Solomon who she was building a connection with prior to Casa. However, Harrison had returned with Lauren Wood and suddenly Cach, Toni, Harrison and Lauren found themselves in this weird/awkward AF/toxic love square.
On day 35, Toni decided to couple up with Harrison, and Casa girlie Emma Munro chose to couple up with Cach.
A few days later, Cach and Ty Isherwood were announced as the two most popular boys as voted by the public with Toni and Yas coming out on top as the most popular girls. Emma was voted least popular girl and dumped from the villa, leaving Cach single.
On day 46, Cach decided to recouple with Toni and the two went on to win the show.
Outside of his relationship with Toni, Cach was close with Ty and Jamie Rhodes. During one particularly sad moment, the cameras caught Cach crying on the terrace over the drama with Toni and Ty was on hand to offer a supporting hug.
