I am a Gemini and my sister is a Scorpio. . . . Will the two of us be harmonious?

According to the constellation, Gemini and Scorpio are opposites. Gemini is good in nature, Scorpio is evil in nature, and it is also the most evil of the twelve constellations. Scorpio is insidious, scheming, scheming, taking pleasure in other people's suffering, scheming, pretending and so on. Here, if you want to live in harmony with her, I think you should first guide her correctly, make her a good person, and try not to let her touch the horoscope. Otherwise, she may be more or less the same as what the horoscope says, because there is a psychological effect called "expectation effect" in people's psychology, which can make them change according to others' expectations under the influence of others' expectations. That's what psychologists say.
