Love in Paradise : The Caribbean — Meet the 4 Couples Featured in the Latest 90 Day Fiancé Spinoff

The 90 Day Fiancé universe is expanding — all the way to the Caribbean.

In PEOPLE's exclusive first look at Love in Paradise: The Caribbean, A 90 Day Story, four couples who met on various tropical islands — Costa Rica, Barbados, Panama and Jamaica — must figure out if their love is truly made to last. The series premieres on discovery+ July 18.

"I met my boyfriend on vacation in Jamaica, he works at a swingers resort on the beach," Illinois-native Aryanna says of beau Sherlon in the new clip.

"Crazy stuff goes on there," Sherlon then says. "The flesh is a weakness."

Next up are Amber, from Florida, and Daniel, based in Costa Rica — "My fiancé lives on a tropical island, I need to go down there to make sure this is the man that I want to marry," Amber says.

"I let Key get away once and I'm not going to let that happen to me again," Californian Mark says of his girlfriend Key, whom he met in Panama.

"I love you but don't rush me," Key says in the next scene.

Through the rest of the teaser, it's clear that meeting on an idyllic Caribbean island doesn't make for a drama-free relationship.

"I haven't seen my man in 12 months," Amber says as she reunites with Daniel. "I'm definitely getting laid tonight."

Later, however, the pair get into an explosive fight. "F--- you Daniel, f--- you," she tells him as she storms out of a restaurant they're dining in.

"I feel like I've been in the dark, because I don't even know who you are," Amber adds to the cameras.

Aryanna and Sherlon, meanwhile, have a more pressing problem. "We didn't use protection when we had sex in Jamaica," she reveals. "A month after I got back I found out I was pregnant."

"Is this your first child or do you have some more kids with some more tourists?" one of her family members then asks Sherlon.

Ultimately, the baby on the way proves to be a strain on their relationship. "I can't raise a baby by myself," Aryanna says through tears, adding to the cameras, "A decision made in the heat of the moment in paradise will impact the rest of my life."

"We both made a big mistake, I'm not going to be forced to get married," Sherlon says.

Mark and Key grapple with closing the distance between them. "I don't want us to be apart," he says, while Key asks, "You are telling me, if [I] don't move to California this relationship finished?"

"Finished — we're over," Mark says.

Elsewhere in the clip, the fourth couple, Miami-based Martine and Barbados DJ Steven, navigate infidelity and commitment issues.

"Steven is a DJ, there are always people trying to throw themselves at him," Martine says. "I want Steven to give me a reason to trust him."

"If a man wants to be with you, he will make it clear to you — like diamond clear," she later tells him, flashing her ring finger, to which he replies, "What? You're on bulls--- now."

"Why the f--- is somebody asking if you're awake at this time of night?" she later asks, though he simply says, "I don't know."

"Steven cheated on me once, I told him, if he ever does that again, I will leave him," Martine tells the cameras before the pair have a heated exchange.

"You be f------ lying," she says, as he asks her, "Can you get out of my face?"

"Or what?" she says.

After meeting three years ago while Amber was vacationing in Costa Rica, she and Daniel are now ready to get married.
