I am looking for verification on what is a plot for a short story.

For example:

A man wants to develop a new rose variety for his girlfriend as a way to propose, but he becomes obsessed with getting the perfect plant and neglects his girlfriend until he almost loses her to a rival.

Or 

A young spy comes home from a mission to find what he thinks is an intruder in the house. It turns out to be his housemate, who is older but he is in love with. Embarrassed by his reaction to seeing the man singing he tries to walk away but gets seen and welcomed home.

Do these have conflict and plot or have I missed the mark? I don't quite get the idea of what is plot and conflict so any suggestions with examples would've gratefully received!
