Real Conflicts and How to Face Them
Emotions vs Logic

Security vs Freedom
Cancer clings for comfort. Capricorn needs space to chase goals. Without balance, Cancer may feel neglected, and Capricorn may feel suffocated.
Mood Swings Meet Stoicism
Cancer changes like tides. Capricorn’s consistent demeanor can seem cold. But sometimes, stillness is love in disguise — both partners must recognize that.
How To Make It Work
