Monkey/Gemini and Dragon/Gemini hit 97-100%, one of the great natural alliances of the whole zodiac. The Monkey and the Dragon are classic allies in Chinese astrology, and doubling the Gemini sun turns their partnership into a permanent festival of ideas.
The Dragon supplies grandeur and generosity, the Monkey supplies wit and invention, and each finds the other endlessly stimulating, which is the one thing both absolutely require. Boredom, the natural predator of Gemini romance, never gets in the door.
This may be the most talkative pairing on the board. Schemes, banter, mimicry, manifestos: the Monkey is never at a loss for words and the Dragon speaks in headlines. They understand each other at a speed outsiders find slightly alarming.
Quarrels are rare and theatrical. The Monkey's teasing can nick the Dragon's pride, and the Dragon's bluster can trigger the Monkey's mischief, but neither can stay angry at their favorite co-conspirator. Apologies usually arrive as jokes.
Monkey/Gemini turns the Dragon's bold visions into workable schemes. Dragon/Gemini gives the Monkey's cleverness a cause bigger than the next trick. Together they actually finish what they start, which neither reliably does alone.
At 97-100%, Monkey/Gemini and Dragon/Gemini are a natural match of the first order. Ally, audience, accomplice, and home, all in one person.
