This is the first seventh axis. sun in seventh house. HIs partners, leo types
However, with Neptune in oppostion, the relationships would be just deceptive, draining, unless he becomes very aware of this polarity or become in tune with the good of Neptune. Metting place of life force and spiritually but from mentioned above, this person has seen too much themselves.
Cooperative with mate and he shines through them. HIs idenity is with his partner, with Neptune opposes it, eventual let down on both sides. This is a hard placement. Ego problems which could be eventually anything. I imagine anyone working with this person would feel eventually let down in some way.
This is also is open enemies. SO I imagine this person has had their share of shady types come and go in their life.
If he partners with someone who has great Neptune qualities with good bounderies. eventually could get it together.
This is their shadow and also life force, the sun. what he does not see well.
They have more than likely had a somewhat difficult life involving people who have let them down, resulting in major ego problems. No idenity, glorified indenity, shapeshifter type, You name it.
OK, this person owns neptune, in his eastern hemisphere, personal. His sun in western is subject to being victimized in some way, giving away his life force.
Narcissitic people live in a world all their own and they USE people. operative word
