Upside: Friends first; childlike and adventurous; naturally enthusiastic; socially curious; colorful, drawn to trends; creatively self-expressive.
Downside: Jealousy and manipulation; putting on a show to get a certain reaction; large friend networks; drama!Element and Quality
There's an undeniable spark between Gemini and Leo -- arguably the two most playful signs in the Zodiac. They're both very social and like to be seen in all the right places. With the world as their stage, they'll be super aware of how they appear together, and may experiment with costumes, personae, etc. They love to date big, go to theme parties, going to nice restaurants, or planning unusual outings.
Both love the new and novel, and their time of dating can be memorable. But Leo wants to be won over, and Gemini is a notoriously distracted air sign. The naturally light in love Gemini may not show enough focused devotion at the outset for proud Leo. Gemini's flirty nature makes jealous Leo roar. Leo wants to be pursued, and may consider Gemini's seductive net more about quantity than quality. There's also the passion factor -- Leo wants ardor, intensity, an epic affair! Gemini is more likely to star in a rom-com, than a sweeping romance.Wandering Eyes
For a longterm relationship to work, Gemini will have to curb the tendency to cultivate side dishes, alongside the main meal. Often they're just flirtations and nothing more. Gemini is a friend to many, and craves social variety.
Leo can also look on love as a competition, and vie for the title of "adored by the largest number." When Leo has that deep commitment, then this relationship has a chance. Gemini's fun, unpredictable outlook brings out the kid in Leo. Leo's solid sense of self is attractive to the more unsettled Gemini. Together they create a vast network of contacts, making it a pairing that could be beneficial in so many ways.
