Hey Cassandra,
There are no dumb questions!! It is always good to ask
I do understand where this comes from.
You could understand -에게 as in To, or Dear.
So in the beginning when you invite someone you could say,
(invitee)에게,
-------
------
-----
(inviter)가 or 올림, 드림 depending on which one you are sending it to!;)
Thank you
