When you do a “love” spell upon someone specific, you are forcing your Will upon that person. It is a form of what is known as coercive magick. Any time you seek to manipulate someone else, you are, in essence, forcing yourself upon them.
Such a love spell is not a binding, and they will not become obsessed with you (unless that is your intent), but it is important to know that any result will only be temporary, as their true Will and feelings will eventually resurface. You said in your opening post that this person isn’t really aware of you, so it seems unlikely there is truly a “connection” for the magick to work with, which means it will have to create one.
A general love spell will work to draw someone to you who will genuinely love you, while a specific targeted spell will not because you are trying to force an emotion that doesn’t yet exist.
That being said, there are plenty of spirits available who can bring him to you if that is truly your Will, like Sallos or Sitri.
Sallos can create love, and eventually draw his heart to you, but it wouldn’t be instantly, while Sitri could help you get him into bed but a long term relationship doesn’t seem to be his kind of thing.
You said you are a beginner in maigck so what kind of magick are you looking for? A candle spell? A spirit evocation?
