Married at First Sightis making series history this season as five couples enter but only four walk away married.

In PEOPLE’s exclusive debut of the season 17 trailer, the blushing brides-to-be are feeling the anxiety as they get ready to walk down the aisle and meet their grooms for the first time.

“I’m getting married to a rando,” bride Emily says after a shot of her growing emotional looking at herself in a wedding dress for the first time is shown.

“What did I get myself into?” she then asks, as a man is heard saying, “If you don’t want to do this, we’ll get you out of here.”

Wedding bells start to ring as a voiceover says, “For the first time inMarried at First Sighthistory, five brides go to the altar but only four come out married.”

The other ladies tear up as they choose their dresses, though inner monologues give insight into the reality of marrying a person they’ve never met.

“I don’t think I can do this,” another bride admits as the camera follows her leaving her dressing room. “I don’t want to marry a stranger.”

“Who will be the jilted groom?” a narrator teases.
