Love and heartbreak are in the air.

Last night’s season premiere of “The Bachelor” was both romantic and emotional, but Zach Shallcross’ journey is just starting to unfold.

In a sneak peek at the entire season, emotions run high as both Zach and the women fall in love.

In the teaser, Jesse Palmer says the season is “an unforgettable adventure filled with love, passion, and romance.”

And Zach is heard saying, “It’s so exciting to be the Bachelor. It feels literally like a dream. I’m here to find my best friend and to spend the rest of my life with someone that loves me and I love them. I know my wife is here.”

Many of the women say that they could see Zach as their husband, with Greer saying, “Zach is the most genuine, emotionally intelligent, sweet soul,” and Aly adding, “After today, I definitely see myself falling in love with Zach.”

Both Charity and Kaity are up in their feels as well, with Charity saying, “I have really waited for this moment to truly experience authentic love,” and Kaity sharing, “Before I met you, I honestly didn’t think that I could be this happy. Zach is the perfect guy. Those are hard to find these days.”

It’s not clear who Zach is speaking to, but he is seen telling someone, “I am falling in love with you and I can see a future with you.”

But amid all the romance, many of the women are also seen in tears, worried that it won’t be them that Zach proposes to at the end of this journey.

Jess is seen crying and telling Zach that she was hurt she hadn’t received a one-on-one date, and Kaity is seen saying, “I’m already feeling jealous. What I have with Zach is amazing and I don’t want it to go away.”

Zach’s suspicions seem to run high as he worries that Anastasia might not be here for him, and Zach says he’s feeling “so confused.”

At the end of the trailer, Zach says, “I’ve caused pain and I’ve made mistakes. I just hope at the end of the day that it’s all worth it” as he walks with a ring box.

But moments later, he’s seen crying and saying, “I don’t know how this could happen. This is just shocking. I didn’t think this could ever be like this. I still love her and it might be too late, but true love is worth fighting for.”

Check out the full teaser below and make sure to tune in to watch Zach’s journey unfold every Monday at 8 p.m. on ABC.
