Luke received Hannah's coveted First Impression Rose and seemed to sweep her off her feet in the first couple of weeks of competition. Luke won the "Mr. Right" pageant during a group date and even interrupted one of Hannah's post-Rose Ceremony interviews to make out with her.
"I would say even just kissing [Luke], there is just this chemistry that is undeniable. There is definitely a physical attraction there that accelerated way faster and off the charts compared to a lot of my other relationships," Hannah shared. "That [shirtless] massage was one of those moments!"
Hannah joked that her mother called her after that scene aired and said, "Lord, bless you."
But in the latest episode, fans watched Hannah ask Luke to back off a little bit. She didn't feel he was respecting her relationships with other men -- and she was turned off by his apparent arrogance, like he had her heart in the bag.
And a teaser trailer released by ABC for an upcoming episode shows Luke screaming in another bachelor's face, which has painted Luke in a villain type of role on the The Bachelorette's fifteenth season.
"I haven't seen [Luke's outburst] before [the trailer]. It's going to be interesting for me to watch some of the things that happen. Because, you know, I only know what happened in the interactions I had with the men and what they say to me and what I feel for them," Hannah explained to ET.
"I don't know what happens anywhere else, so, to see some of the things in the teasers, I'm like, 'Huh! Interesting.'"
"I think it's possible I didn't know the extreme of [Luke's behavior]," Hannah said.
Luke was the first bachelor to tell Hannah that he was falling in love with her, but since he only waited until Episode 2 to say so, everyone has been skeptical about his feelings and true intentions.
So did Hannah actually believe Luke when he professed he was falling in love?
"In the moment, he was the person with [whom] I had the first connection -- a real, indescribable connection with, I would say," Hannah admitted.
"And so, if anybody was going to say it, I would more so believe Luke out of anybody. But even when he started talking, I was like, 'Yeah, he's saying it. Oh God, is he really saying it?! Yup. You said it.'"
Hannah couldn't help but be flattered by Luke P.'s vulnerability and public declaration of his almost-love.
"So part of me was giddy and like, 'Oh, this guy I'm starting to like more than likes me -- but likes me at least.' So there was excitement in that, but at the end of the night, I started questioning it a little bit too," Hannah explained.
"So yeah, there was a part of me that questioned it a little bit, but also, I'm there for people to start developing feelings for me in this quick pace. And so there was a part of me that was a little hopeful... It was quick. It was real quick."
Hannah confessed it was "really awkward" a handful of men were present when Luke opened himself up like that onstage in front of an audience at the Mr. Right pageant.
"It was awkward in the moment, but honestly, a part of me was like, 'Oh, I'm glad this guy likes me.' But that's more than 'like' and now everybody knows how you feel," she noted.
Hannah revealed on The Bachelorette she is the type of woman who tends to zero in on somebody she likes and pursue him whole-heartedly, and so she told ET she had to actively stop herself from doing that with Luke on the show.
"I'm not going to pretend it's not obvious I'm, like, [drooling over] Luke P. Like, I am! And so, I was really struggled in [the beginning] with, 'Hey, it's not just Luke P,'" Hannah said.
"But I think him being like, 'I'm starting to fall in love with you,' was like, 'Yay,' but also, 'Alright, that's a lot at the same time. Let me not go all in like that right now, because if I do that? What am I going to do the rest of the time?'"
Hannah continued, "So I really did have to pump the brakes with him for myself because, yeah, I am someone that would just zero in on somebody. And the way it's looking right now, Luke P. was really easy for me to zero in on it. Our emotional and physical connection is far beyond the other men... You'll have to see [if the other guys catch up."
