i'm not sure what this will mean to you but just out my head ere's just a couple things i see...chart ruler is neptune which he has conjunct his mc in the 10th house. he may be good with helping people out (and possibly has a hard time saying no to anyone in this regard). he also might be dreamy or confused when it comes to his outer world. is he just an acquaintence of yours? acquaintences could be considered a part of one's outer world so maybe he's just gettin all dreamy about ya hehe.
in a year or 2 he'll be going through some big relationship changes a la saturn in virgo in the 7th (conjunct the dsc) plus it's his only earth sign. it's also conjunct his n node.
could he be a very outgoing and maybe even 'showy' talker? (merc conj jup in leo) he may be able to attract a lot of attention by his speaking.
mars and venus, not conjunct, but both in gemini. super playful and flirty but not so obvious since of his watery big 3.
he's probably walking circles, at a distance, around you. pretending not to pay you any, or at least not too much attention, but really he may have his eye on you all the while. does he talk to people around you and sort of glance at you to see if you'll notice?
anyway, have fun with it

`Who are you?' said the Caterpillar. This was not an encouraging opening for a conversation. Alice replied, rather shyly, `I--I hardly know, sir, just at present-- at least I know who I WAS when I got up this morning, but I think I must have been changed several times since then.'
