Scorpios are intensely private. Their deep emotions and motivations are often obscured from others.

Cancers are sensitive and protective of their inner world. Only those closest gain access to a Cancer's true self.

Independent Aquarians reveal little and value their freedom. Their unpredictability adds to the mystery.  

Capricorns are guarded over their vulnerabilities due to a fear of failure or betrayal.

Dreamy Pisces have a rich inner world that even they struggle to decode. Their evasiveness adds to the enigma.

Virgo's perfectionism causes them to be highly self-critical and unlikely to open up to others.

Scorpio, Cancer, Aquarius, Capricorn, Pisces, and Virgo are the most mysterious, complex zodiac signs.
