Peter Kraus has quickly emerged as an early frontrunner on The Bachelorette -- and Rachel Lindsay isn't trying to hide the fact.

As shown on The Bachelorette's Season 13 premiere, Peter, a 31-year-old personal trainer and business owner from Madison, WI, stepped out of a limo first to introduce himself to Rachel, and she called him "cute" when he walked away.

At the Rose Ceremony on Night 1, Rachel also handed Peter a rose before any of her other suitors.

Rachel and Peter's relationship is heating up, as the pair enjoyed the first one-on-one date of the season during last week's second episode.

Not only did Peter get to enjoy Rachel's company, but he also bonded with her adorable dog Copper during a playful outing to Bark Fest. 

Rachel gushed about how handsome Peter is and how she rarely gets butterflies -- but he managed to put that feeling inside her stomach.

Rachel definitely sees potential in their romance, and Peter admitted he could envision spending the rest of his life with 32-year-old The Bachelorette star.
