"It was really tough for me to decide who to give the rose to. I had a great conversation with [Ben Scott] where we shared stories about our childhood and our interests so I felt I had more invested in him," Hartsock wrote in her People blog.
"But I didn't realize how giving it to him would affect the others. I feel for Sean Lowe a lot more now knowing how difficult it is to hand out roses on group dates."
Hartsock -- who had competed for Lowe's heart during The Bachelor's most recent seventeenth edition -- had little to no hesitation, however, when determining whether she should give roses to Brooks Forester and Bryden Vukasin on their one-on-one dates. Hartsock loved Forester's fun, playful personality.
"For that first date, I wanted someone who could be spontaneous and turn a seemingly awkward activity into fun and laughter. Brooks was the perfect choice," Hartsock explained.
"The best part about the car ride to the Hollywood sign with Brooks was our engaging and fun conversation. The natural banter and comfort we had continued and made the date so special... Dancing in the moonlight to Andy Grammer was the cherry on top. I was the happiest person alive after a successful first date."
Hartsock also thought Vukasin had some similar great qualities she's looking for in a man, including his ability to let loose and enjoy every moment.
"I love road trips -- they're the best way to get to know someone you are dating. I have discovered red flags with exes while on road trips so I was interested to see how Bryden would be. He is very easygoing and also a little mysterious, which drew me in that first night," The Bachelorette star wrote, adding that he brought out her nurturing side that night when describing a terrible car crash he had been in during his college days.
"While looking at the pictures of his accident and hearing what is was like to be hospitalized, all I wanted to do was take care of him. There was A LOT of build up for that first kiss -- and I'm glad the night ended on a solid note."
Also in her People blog, Hartsock teased what's to come next week, and apparently drama in the house comes to a head.
"I didn't even think there would be drama this early on. As I'm sure you know, I only see what happens right in front of me, so I'm just as curious as all of you to watch it unfold... Next week's events are unlike anything you've ever seen before. I always fear that someone isn't here for the right reasons -- fortunately this liar gets caught. There is unbelievable confrontation, men playing rough, and sexy cowboys," she added.
