What constellations are trapped by love, like to say nothing, but secretly pay attention behind their backs?

Cancer is a person with rich and delicate feelings. But cancer has a very prominent personality, introverted, shy and not very expressive. What worries and habits are hidden in my heart and will not be easily revealed, so I can't see Cancer expressing my thoughts at ordinary times, and it will be the same when I am in love. Obviously, you love, care and feel the depth of the ocean.
