Loran's relationship with Drake is pretty straight forward. He represents the one thing she always wanted in life, someone to see her as a person, not a magical weapon of mass destruction or a Demonic freak, to which she shows him the same kindness, looking past the harsh reality of what he is and seeing only the human aspect.
She had developed romantic feeling for him, but still is unsure of if it could work out between them, even though this is the closest she'd ever emotionally been to another human being. She fears that she'll end up causing him heartache and suffering in the long run, and therefore has elected to take it slow for now.
After being with Drake for months, Loran seems to have eased into the relationship, and no longer tries to bottle up her emotions concerning the young man.
