What kind of constellation has a little devil in its heart?

Gemini has two sides, one is dark and the other is kind. He will always be a kind and gentle man in front of outsiders, but once annoyed, he will turn into a demon and take revenge on you crazily.

Capricorn. Compare CAPRICORN

There are two forces in Capricorn's heart, angels and demons, but they are not in conflict. Because you are kind to her, she will repay you like an angel. If you treat her badly, she will get back at you severely. So Capricorn people are kind, but they are not easy to bully others.
