I would also like to come out and say that even though I vote for Dating, I pretty much agree 100% with what
@TenfoldShields was saying. Eldingar doesn't really strike me as the type who wants to wait for a true love's kiss and be with that person forever because watched way too much Disney as a kid. Especially considering how he dreamt of getting swept away by a sexy incubus when he was younger (oh fancy that, an old wish that can be fulfilled), those aren't generally known for being steady boyfriends.
There's always the question of how much the personality of a Quest's protagonist that can be molded by the voters, but Zerban's generally tend to have strong predetermined personalities and there's a plan for where they're going (and if anyone don't believe he planned this, take a second look at the tags).
It's also definitely true that sex is almost always a/the climax of the love story and almost never something that happens near the beginning, which makes a story that doesn't do that naturally interesting. And I have no doubt Zerban can pull off such an "unusual" story.
Of course, that's also part of the reason I vote dating. I like having it used as a climax that signifies the end of a lot of trials and tribulations for the couple.
(also, this is openly a harem quest. If you're afraid we're getting locked into a single route before 5 of the people from the opening music video have shown up, you're being silly)
