I'm not experienced enough to read this chart as you'd probably likeIs that birth time correct? Midnight?
If he's born a few hours later or any other time later than 3am he's a Leo moon. Off the top of my head I have read/experienced aquarius with Leo moons having a hard time letting go of even bad relationships.
One of the first things I do to introduce my friends to astrology is send them their astrology-numerology.com sun/moon combo.
Or show them astro click on astro. This chart seems like it might be a generic time though so Im wondering if the house placements apply to him?
If the birth time is right he is a fire void
