Johan works at a resort in the Dominican Republic and his job is to entertain. This means that entertaining women is also part of his job. This is how Charlotte met him.
Even though Charlotte knows that she wants to spend her life with him, she has gotten a little nervous about how he treats the women that he works for. In fact, the producers of the show revealed that they know more about Johan than Charlotte would like to hear.
It turns out that Johan has been seeing another woman at the same time he has been with Charlotte. A woman came forward to the production team and they had to tell Charlotte that this woman claimed to be sleeping with Johan.
As soon as she heard this news, she went onto social media and asked her followers if they knew anyone who had been with Johan, she would like for them to come forward. This led to more women coming out about their relationship with Johan.
