ABC's "Bachelor in Paradise," host Chris Harrison and a studio audience watched the four remaining couples in the three-hour finale of season 6 bringing both joy and heartbreak.

Demi and Kristian, Chris and Katie, Dylan and Hannah, and Clay and Nicole have the choice to spend one last night in the fantasy suites. For Clay and Nicole, it was a fork in the road as Clay decided not to go to the fantasy suite, and ultimately couldn't reciprocate Nicole's love.

However, the other three remaining couples walked to the beach for a final rose and proposals! The heartwarming love between Dylan and Hannah, the two became fiancés after Dylan proposed and Hannah said, "Yes!" Two more engagements came from proposals of Demi to Kristian and Chris to Katie.

When the couples appeared in studio, it wasn't joy and wedding plans for one couple. Chris said he was blindsided by Katie's disclosure of their relationship troubles. At the end of the discussion on stage, Chris put the ring back on Katie's finger. Moments later backstage, the couple were arguing again and ended up walking away from each other. Looks like it's a wrap on their relationship and season 6 of "Bachelor in Paradise."

In front of the studio audience, Demi got a proposal of her own from Kristian with a beautiful diamond ring from Neil Lane. 

Congratulations to the newly engaged couples Dylan and Hannah and Demi and Kristian!
