In a romantic relationship, these two share a strong kinship, according to the twins. As they previously wrote for mindbodygreen, when signs share an element, they feel like they don’t have to explain themselves to each other—they just “get” how the other works.

So for Pisces and Cancer, you may have never felt so comfortable with someone, they say, adding, “This is the person you can burp and fart around or pee with the door open when they’re home—but don’t invest in a wardrobe full of elastic waistbands just yet.”

Because while, of course, having a partner and built-in best friend in one is great, it’s not always a recipe for passion, and the twins note these two might need to work a bit harder to keep the spark alive as a result.

But considering these two watery signs are more concerned with emotional connection, that’s might not even be a cause for concern. As the twins note, Cancers totally give “mama bear” energy, while Pisces is more than happy to soak up that love and give it back in return.

These two signs are also highly intuitive, so there’s a strong possibility here for an almost psychic connection of understanding. “They really know how to work with the energy of difficult, charged emotions that can come up in relationships or a group setting,” the twins add.

Overall, this is a romantic relationship characterized by deep emotional receptivity, shared intuition, and a lot of adoration. As long as they don’t get too bogged down by their emotional waters, this is an astrological matchup that has major staying power.
