Love potion idea wasn't permanent. Like I mentioned,
it would last like...for a set amount of time, in which
the person using it had that time to try to make the
other character truly fall in love with them, and if
they failed, then the other character's horse just
forgot about them after the potion wore off. And also,
there was the antidote to a love potion I suggested
as well. And I'm sure you could always work something
out with a player who actually had a love potion and
tell them you really didn't want them to use it on
your character.
