Gemini June most likely were born under the influence of Venus/Uranus and Pisces March were born under the influence of the Moon/Pluto (depends on which date you were born). I assume, as a mutable sign, both of them understand the importance of freedom. Too much intensity in a relationship could lead to both being overwhelmed. They will be a perfect match if both only crave a temporary relationship (which only has a lot of fun). Pisces loves to share their activities with Gemini as well as Gemini itself. They enjoy each other's company more than anything.

Pros: Understanding each other's freedom without asking

Cons: Brushing off the problem is not a way to solve the problem. Tolerating does not mean abandoning the problem in the form of love. Stop hiding behind: "I let it slide because i love you," and actually address the problem before it gets out of hand!
