Story about a man who trusts and loves his girlfriend.

Basic premise is that your girlfriend is leaving on a trip and wants you to take part in some mysterious course while she's gone. Figuring out what the course is about is a big part of the story.

Mostly the story will be focused on dialogue and thoughts. One of my goals is for there to not be any potentially interesting conversations that are skipped past, many times I've been reading some story and hated it when some really interesting conversation is just summed up without going into enough detail.
