I think the number of secrets may depend on personality. For Aquarius, Aquarius is a deeply buried constellation. On the surface, Aquarius is hot and cold, in fact, because they are very proud inside. No matter what you say about them, as long as you don't use negative words, they will take it for granted that you are praising them. In their hearts, they will silently attribute these to you not understanding them, but don't blame you.
On the surface, Aquarius will not show up. This character can be said to be proud, always looking for the feeling of knowing each other. It seems that they are free and easy, rebellious and willful, but in fact, they will have their own rules in their hearts, so no matter what they say, what is good will come down to you not knowing them.
So if you want to say the most unspeakable secret of Aquarius, one is their deep pride, and the other may be their own rules. As long as it is within their rules, they basically don't care. If they pass, Aquarius will never have a good face. After all, they usually say and even resist things they don't like.
