I can see some harmony and some tension. The harmony is placed on your ascendants, although your jupiter signs square each other, you view the world as a scenery in diferent ways, but the way you come up to each other is pretty similar, and also the opposite suns create some attraction at first, and with his sun on your IC, making him seem kinda familiar to you.
Mercury opposite would help or not so, to communicate between you guys might be a bit harsh at times. But he's a very understanding and compassionate person with pisces venus. and his moon to your mercury helps communication, he feels pretty much what you say, and being around pluto... oh boy
Moon venus also, very good aspect. Very pleasing to one another.
Your mars square his suns generates a bit of a spark, attraction, which might attach you to one another. His mars to your sun creates pure harmony, this one is surely positive.
Watch for the opposite suns as there are two opposite wills facing each other, and saturn to his North Node, it might sometimes play like he being like a father to you in some way, or the other way around
Watch for his saturn to your mars, moon and sun, its binding but creates constrain and limits yourself. You guys just have to balance between the good and less good aspects.
Ascendant to your North Node, dunno exactly but maybe you've see each other before... somehow... this one is very outstanding
