You know, I have done some pre-planned romances, and they worked well, but it wasn't before the characters even started to grow and intermingle. I feel like planning, to some extent is great, but only if you look carefully at what the writing styles are like, what the characters would be like and whether or not it would even be appropriate considering character background. Organic is just better in a game filled with people making long posts in styles that are completely different from eachother. (Except perhaps for myself, I think Vergil might recognize the style of describing the fights as distinctly someone else's, but with a little more grit.)
