There is a common trope in movies and television of two people who cannot stand each other eventually falling in love. In astrology, this trope is most common in relationships with the Sun square the Sun.
Other Synastry Aspects
Solar aspects can be quite complicated, however. This is because Mercury and Venus are never far away from the Sun in any birth chart.
While the Sun represents one’s ego and individuality, in many ways Mercury and Venus are more important when it comes to relationships. Venus is the main planet that governs relationships, and Mercury governs communication.
When the Sun is square the Sun, Mercury and Venus may also have squares between them or each other. If this is the case, the aspect will be even more difficult and tense.
On the other hand, it is also possible that there are sextiles or trines between or among these three planets. In this case, those aspects will absorb and mitigate the tension.
It could also be the case that there is a complex mix of sextiles, squares, and trines between these planets This generally makes for a complicated and messy relationship.

Sun square the Sun in a romantic relationship can bring people together. The tension from this aspect can generate a great deal of physical chemistry.
The problem is that it can also be a huge barrier to them being able to stay together. Sex, no matter how good it is, can only carry a relationship so far.
It will take a lot of energy and work for them to get along with each other enough so that they are not constantly locking horns.
In advising a couple with this aspect, it is important to look at the other aspects they have between them. Trines and sextiles, especially involving Mercury and Venus, will help a lot in terms of smoothing over the rough areas of their relationship.
Other squares and oppositions, especially if they involve Mercury or Mars, will make the situation worse.
It is not uncommon for people to be drawn to others who challenge them and touch the sensitive places in their charts. On a spiritual level, these types of relationships do help people to grow and work through their issues.
On the other hand, to get the most out of tough synastry aspects such as Sun square Sun, it is necessary for both people to be willing to set aside their egos and their pride to listen and adjust to someone who is different from them.
A good sense of humor and the ability to laugh at oneself and the stresses and frustrations of being in a relationship will go a long way towards easing the situation as well.
Sun Square Sun in Friendship
The most natural effect of Sun square Sun on friendship is that it will prevent one from forming in the first place. Even in the best case scenerio, this aspect creates tension between two people that is not easily resolved.
This is because the tension goes to the core of each of their personalities. They are each annoyed by the very essence of who the other person is.
If a friendship does form between two people with this aspect, it will be because of other, more harmonious aspects between them. Sun square Sun will still create friction between them, but it will be overcome by other aspects.
There is a special danger if a friendship forms between two people who are of the right gender and sexual orientation to make a romantic relationship possible.
This danger is that one or both of them feels attracted to the other person. In this case, the attraction could be strong enough to overpower reason and good sense.
If this happens, it will be important to exercise caution before acting on any such feelings.

If the Sun is square by sign, this aspect will have some effect. The closer it is to exact, the stronger and more difficult it is.
The orb, or allowable margin of error, for the Sun is seventeen degrees. If this aspect is within this orb, it will be fully present.
With such a wide orb, cross-sign squares are common. In general, the boundaries between signs can be seen as very thick walls, especially when it comes to the Sun.
Unless, the cross-sign aspect is really close, within about three or four degrees, it is safe to ignore it in a synastry reading. If it is close, it will add tension to what would otherwise be a harmonious whole-sign sextile or trine.
