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.

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.

Genres I should clarify a bit:
Romance, one of the main things even if this isn't a typical romance novel.
Mystery, no murder mysteries though mysteries are an essential part of the story.
Gender Bender, no actual sex change, feminization might be more appropriate if it was an option.
Harem mainly means that characters other than the main love interest can have feelings and do things.
Ecchi/Adult, most of the story has sexual elements but actual sex should be rare.
Comedy, I find myself wanting to make things funny when I can but I didn't set out to make this a comedy
