When Gemini and Leo start a love relationship, it’s a rather high-spirited and playful relationship powered by optimism and joyful activity. Gemini loves intellectual stimulation thereby attracting them to Leo’s dynamic yet creative spirit. Troubles arise when Gemini feels that Leo is trying to establish dominance and when Leo begins to consider Gemini’s flirtatious approach too seriously. Leo is a fixed sign and Gemini is a Mutable sign. Leo is stubborn, rigid, and resolute in their ideas, ideals and actions. Gemini is extremely flexible, and they can change their viewpoints at the drop of a hat. Both these signs share a youthful, almost childlike worldview. Therefore, this pair can be greatly successful due to their inherent optimism and curious natures.
