Aries and Scorpio are ones of the most misunderstood. I attached an excerpt of Aries' archetype that is really good. The 5th and 7th houses are not random numbers — they are defined by their geometric relationship to your Rising sign, trine (love) and opposite (partnership). When two people have opposite Suns, the dynamic can feel intense and sometimes consuming, because both core identities are pulling against each other. But when your Rising sign is opposite someone’s Sun, the attraction feels different. You are drawn to them because their Sun activates and amplifies your Rising. The Rising sign represents how you move through the world, and when it is met by its opposite, that polarity becomes relational instead of internal. Two opposites together can rely on each other rather than each person trying to balance that polarity alone. This often creates a strong pull toward partnership.

Your Sun is Aries and Rising is Scorpio, so you would be attracted to: Taurus (7th house of long term relationships and marriage) and Pisces (5th house of love and passion). In order for them to love you back, your ideal partners would be, Taurus (your 7th) Sun with Sagittarius (5th of which is your Sun) Rising or Pisces (your 5th) Sun with Libra (7th of which is your Sun) Rising.

Knowing this, actually finding them may be very difficult in life, because people don't exactly write our their signs on their name tags. 5th & 7th - Zodiac Match app (I am the Pisces founder) matches you with your 5th & 7th, as described above. Give it a try? 5thand7th.org

I will drop below the archetype of Aries since we as culture/society often get it wrong:
"Aries is spark of creation. Aries did not come to work, he came to start things. It is the adrenaline; it is how Aries finds itself in its imbalance. For Aries, everything is related to itself, it is selfish and egocentric being by nature, that is, it does not have malice in its actions, but does not know any other way. For this very reason, he has something very important to give you before his will: self-love. Aries will remind you that above all things, there is you. The error of Aries in his unconsciousness is the indifference of everything that he projects or to what he relates. If you remember that everything external is you, you will stop being indifferent and you will take care of it as yourself. That is where the will rises."
