The suit of Cups represents water. Water is the flow of emotions, creativity and love.
 
The Twos in the Minor Arcana are about balance and seeking to combine different energies.
 
The Two of Cups can represent the flow of emotions between two people. It may mean romantic love or a true meeting with a soul mate or twin flame; someone that can build you up; someone that longs to entwine their path with your own; someone you can build a life with.
 
Sometimes the Two of Cups represents a truly supportive friendship with a person that always has your back; someone that you can depend on no matter what circumstances might arise.
