I don't see any soul-crushing, mindblowing compatibility between either of the two synastries.
In the first chart I see:
His Venus trines her Moon, and it also trines her Pluto
His Venus closely conjuncts her Neptune.
Her Venus opposes her Neptune/Mars conjunction (strong attraction + idealization)
Moon in Pisces and Moon in Scorpio are both water signs, compatible
His Mars and Jupiter opposite overlaps her North Node-South Node axis
In the second chart:
His Venus closely conjuncts your Neptune. This means he idealizes you and projects on you positive qualities you might not even have. This is a strong sign of attraction. (But this happens with the other girl too, you are nearly the same age, it's generational)
I like how your asc/desc axis almost overlap and are in opposite signs. You are a Pisces asc and he is a Scorpio asc, both water signs.
Moon in Sagittarius and Moon in Pisces - different elements, Fire and Water, not really compatible
Your Mercury is close to his Moon, that helps communication
Your Venus falls on his MC and opposes his Pluto, that is sexy but also control issues can arise
His Moon is on your MC
Your Sun opposes his North Node and conjuncts his South Node (possibility for growth on both sides, meaningful relationship, maybe karmic connection)
