'The Bachelorette' star Jenn Tran teases her season's 'very surprising' ending: 'It was a shocker for me'

• Jenn Tran gets another shot at love on season 21 of "The Bachelorette."
• Tran described her season of the reality TV show as adventurous, emotional, and surprising. 
• She said the season 21 ending is shocking and one she never saw coming. 

"The Bachelorette" star Jenn Tran promises that fans are in for plenty of shocking moments during her season of the long-running reality franchise, particularly at the end of her journey.

"It's adventurous, emotional, and very surprising," Tran told Business Insider ahead of the season 21 premiere.

"Of course, there's going to be some crying, some dramatic moments. And it's adventurous because I was really pushed outside my comfort zone," she added.

Bachelor Nation was first introduced to Tran earlier this year on season 28 of "The Bachelor," where she was eliminated just before hometowns. Now, Tran gets another shot at love as the leading lady of "The Bachelorette."

In addition to making history as the first Asian-American Bachelorette, Tran's season has other changes — like ditching the Bachelor Mansion for a brand new residence and immediately traveling abroad after night one.

Being the star of her own show was an adjustment for Tran, who had never been in a serious relationship that was headed toward a commitment. Figuring out what a serious relationship could look like on "The Bachelorette" was a learning experience.

"There were a few instances in which I think I had a lot of fun and good banter with the guy, but I wasn't sure if there was more there," Tran explained. "And as we got to have more and more conversations with each other, I realized that there was so much depth there and that we had so much more in common than just our ability to laugh with each other."

Given that the franchise has been around for more than 20 seasons, it's hard to imagine anything happening this season that could break the mold. But Tran recently teased in an interview with former Bachelorette Kaitlyn Bristowe that the ending of her season is "something that has never happened before."

When BI asked her to elaborate, she offered a few more details. "I came into the journey kind of thinking that it would end in a certain way or a different way," Tran told BI.

"The ending of it all, I just never really saw coming," she added. "So it was a shocker for me, and it's going to be a shocker to my family, and I think it's going to be a shocker to a lot of people watching as well."

"The Bachelorette" season 21 premieres on Monday at 8 p.m. ET on ABC. Episodes stream the next day on Hulu.
