The 9th house is the house of worldview, the sphere of religion, higher education, and long-distance travels. Venus is the planet of our feelings, and the 9th house is our worldview, a high one. Therefore, a person with such a Venus will be drawn to elevated feelings, such an idealistic state will be towards their partner. They need to admire their loved one. To understand this Venus, I will give a clichéd plot. Let's say a girl has created an image of her loved one and is waiting for a prince on a white horse who will come to her, extend his hand, and carry her off to beautiful faraway lands. A rather romantic young lady. Therefore, here a person can fall in love with an image, be charmed, endow it with qualities that it does not have, and then, possibly, become disillusioned. But again, the aspects, the connection of the houses are very important, with the presence of tense aspects, disappointments are inevitable, and with harmonious ones, everything can be fine: for example, they will fall in love with an educated intellectual, or with a foreigner. Venus in the 9th house is optimistic and positive. And even if the aspects are tense, in general it is tuned to the best.
For Venus in the 9th house, the spiritual connection, the ideological community of views on the world, is more important than the passion in the relationship.
The loved one and the relationship with the loved one in general can influence the worldview.
A person with Venus in the 9th house loves to learn very much. And they will learn precisely what they like, read books they like, travel with the aim of obtaining some emotions, not for the sake of lying on the sea, but precisely the desire to explore another culture, broaden their horizons, absorb new knowledge and receive emotional satisfaction.
The 9th house is the house of education, primarily higher education. And as mentioned earlier, they love to learn, but only what they like, what ignites them. Therefore, if a person is studying, and suddenly realized that this is not what they wanted, then most likely they will not complete this education. They will not be able to study if there is no this emotional involvement.
A person with such a Venus may fall in love during travels, romantic relationships may develop abroad, or there may be relationships where the person studies.
