Are you sure you have read the ToZ site and what it says about witchcraft?
There's no such thing as a "fast-acting spell" because a spell is merely a tool to focus your own powers, not something that has power from its own. It depends on your own spiritual power.
If you are spiritually weak, then spells will take a long time. You will have to do them every day for more than a month, not just one time.
A fast-acting spell is any spell you do while you are spiritually advanced. Because then everything will manifest quickly.
But it's obvious that you are no advanced as you are looking to use a targeted love spell. Only newbies and inexperienced people want to use a love spell on a specific person.
Experienced people understand that it's better to use a generic working to attract your perfect partner and not a love spell targeting a specific person, because you don't even know if that person is for you. 99% of the people who use a targeted love spell act impulsively from an obsession with a specific person, and most of the time that person isn't for them.
Seriously, forget that person and just do a generic love working to bring your perfect partner. If that person you're obsessed with happens to be the right one, then the working will bring them to you, regardless if they go on a trip or not.
