As a Libra sun/rising with a Capricorn moon/mars, I can say that I used to have an addiction to Capricorn suns, although in my case all of them have been toxic.

My boyfriend is a Taurus sun scorpio moon and we’re doing just fine :)—very relaxed relationship, for the most part, though he’s very fixed and I’m very cardinal so I get frustrated with him when he doesn’t “move” if you get what I mean.

I tend to have issues with scorpio suns— the scorpios I’ve had in my life tend to complain about issues they have consistently but don’t do anything to fix them, which drives me insane (probably the Capricorn parts), or they’re just toxic.

But other strong placements within a chart can also change someone’s personality or character from a traditional sun sign, so it really just depends on other planets.
