Paul and Helen. Believable and real.
Grace and Mikey. Not believable to me at all, Grace came across very camera aware but they've proved it was real because they're married now.
All the others were pretty much showmances or just fancying each other a bit. Couples in scripted shows are more real.

Remember Ziggy? Sweetened Chanelle up, fucked her (without realising Carole was in the next bed, then dumped her.
And then got a lecture about not using condoms lol
