Jennie Cederlund, Fredrik Brännlund, Sofia Strömberg and Rasmus Holmgren are the new additions who are now moving into the "love house" and are thrown straight into couples therapy, vow ceremonies and exercises with the other couples and the programme's experts.
It certainly felt like you were stepping into something that was already under way. They had to fast-forward things for us to catch up on a lot, so it was generally a very fast pace, but I loved every second of it,” says Fredrik Brännlund, 34.
How did the other couples react?
"I felt that we were stirring the pot a bit. The group's collective culture made it feel like entering North Korea at first, but then when you got to know each individual it was very nice," he says, adding:
I also believe that, to some extent, we could contribute fresh eyes and a challenging perspective on the other couples' relationships.
A taboo
One of the couples in this year's season, Helena Vanhanen and Sasan Momeni, has chosen to leave the experiment early. Momeni's view that you can't have friends of the opposite sex - an opinion it turned out several of the participants shared - was the final straw.
Fredrik Brännlund thinks it is good that the issue has come up and led to debate.
I've heard people who have talked about the programme say, "Yeah, but that's how it is, but you can't say that out loud." It's undeniably a taboo, where there are polarising opinions, and then it's really important to talk about it, he says.
Where do you stand on the matter?
I understand that it comes from fear and insecurity, and I can relate and sympathise with someone who has those opinions, but we can't keep domesticating each other.
Useful debate
Many viewers have reported the programme to the Review Board and believe that SVT is failing in its public service mission when opinions perceived as misogynistic are allowed to remain unchallenged. Fredrik Brännlund disagrees.
I think it has become a useful and healthy debate even though the opinions are highly debatable. That's what public service is for, to untie knots in homes and between couples and get people to watch things they don't dare to watch and have discussions, that's the most important thing there is.
