Well I think that there are some of the marriage candidates that are kind of supposed to be together until the farmer shows up. (Based on the flower dance partners)
Sebastian with Abigail - Pretty obvious childhood friends to lovers (I think)
Sam and Penny - We have a troublemaker falling in love with the quiet beauty that usually reads under the tree next to where Sam lives (quite a cute relationship

)
Alex and Haley - If Alex eventually realizes the hints Haley is giving

Elliot and Leah - Though I fell like maybe they are just really close friends
Harvey and Maru - Have potential for a work place relationship, but personally I don't think it will ever happen
Emily and Shane - Being completely honest I think Emily is just close friends with Shane probably due to him being a regular at the saloon
If Sandy was not stuck working in the desert, due to some shady Qi related reasons, I fell like she would be a great couple with Emily.
As for Krobus, he's there to comfort us and to support us as the best roommate ever.
