Which constellation is Gemini most similar to?

1. Aquarius ~ I feel very tacit and the topic is similar ~ Both boys and girls will feel that some places are very similar. Anyway, it's two constellations that hit it off.

2. Gemini ~ Of course, there are still many similarities between two identical constellations, but there will be exceptions. Many Geminis I know have completely different personalities, but it's not surprising.
