Four couples on the brink take a 2-week trip together. Nervous about the change? The dinner is with their partner's date... and their date's partner!

Each couple has their own issues behind those smiles. But amidst the tension, people are scheduling their second dates — right next to their partners!

You get me. You make me laugh. This feels different. The second date is going well for those who hit it off. But what about the ones they left behind?

The second dates brought everyone closer. But tensions between their actual partners explode. And now, the women must choose their first dates.

The women have chosen their first dates. Sharing food and stargazing is a whole new experience. Comfort is one thing, but butterflies are even better!

After the date, anxiety abounds as the switched-up couples play pool. Many are left wondering: Were they always this nice? Jealousy's hard to hide.

This time it's the men's turn. They must request a change date without anyone's partners finding out. Later, a light-hearted drinking game goes south.

The final decisions loom near. The men choose their dates. Some smile for no reason while others hold hands on the beach. What are these butterflies?

Their partners with another date... Everyone's only imagined it! But now it’s for real. Can these shattered hearts amend their original relationships?

This is reality, and it’s hard. There might be tears. The couples struggle to face the music. And in the quiet dorm, an interesting message arrives.

They cook and laugh by the fire. Camping makes them forget their actual partners. On a beach, one man captures on film the one who captured his heart.

Time passes as the moment of truth approaches. The women and men gather separately, hackles and glasses raised. They’re seeing red. Who will it be?

The women return to their rooms in shock. Our partners have to move out? Some shed tears, while others happily pack up to go. How will this play out?

Day 2 has begun. How does my partner feel? Should we stay together or try dating someone else? Time passes slowly but surely amid all the questions.

Will we ever be the same? The original couples unburden themselves before the final change date. But when the time comes, some hearts are unaligned.
