I had an idea for a Demon: the Descent character who runs an online dating/matchmaking service. The idea would be that the exchange agreed in the pact/Terms of Service would grant the mortal the True Friend merit (CofD: Chronicles of Darkness: Revised Storytelling System Rulebook, p. 56) in exchange for something that I could secretly take from them and patch onto my character as needed.
From what I remember, granting a three-dot merit was a simple pact that provided plenty of benefits (I can't double check this as I haven't got access to the rules anymore, but hopefully shouldn't affect the question).
But assuming I can grant one mortal NPC the True Friend merit specifying another NPC, does that implicitly create a two-way bond between them?
If I recall correctly, the text of the merit implies that if a PC has the True Friend merit and she doesn't uphold the relationship, she might lose the merit but does not state that she's beholden in the same way, i.e. the 'True Fiend' NPC doesn't have their own 'True Friend' merit.
In short, would the pact need to give one or two merits - one to each NPC - to function as I'm intending (i.e. create a functional friendship that I can nudge into something more)? My argument is, so long as they both get a True Friend out of it, there won't be repercussions on my character, and it's simpler than patching a whole relation in out of thin air onto the mortal (which I think is possible but more complicated for a pact, but I forget how exactly).
I want to avoid the situation where the relationship is one-way between the two mortal NPCs.
