Actually, I think most of them are romantic paths. There's an affective bound with each girl if you focus on her. I mean, Ellen's story evolves into a real love thing, and Victoria 'non Spellbound' path is also a love story. There are a clear romance with Abby, and of course Sonja's second chance can only be understood from love feelings. Only Chandra remains as a casual sex thing (at least from MC pov), but most probably due to her lack of presence so far. It was the same in Depraved Awakening: after all those apparently random sex encounters, in the end you have actually had a real romance with the 'main' girl you chose
