I've never said that Natsu and Lucy are in love that is why I said more or less as each person sees their relationship differently but I could have worded it better on my part. This is a comparison between Natsu/Lucy and Zeref/Mavis (and yes I know that the blonde thing is considental but thanks) both individual pairs and to each other in a number of ways. I put Lucy's magic in comparison to Natsu's Fire magic/curse for a number of reasons such as Lucy's keys glow light when used, celestial spirit magic is connected to the stars/sky which is usually considered a divine place (gods/Angels). Natsu is demonic as he is a demon and curses are evil or bad and fire is sometimes related to hell or the underworld. This whole point was to show that Mavis and Lucy represent light by both their magic and personalities in comparison to Zeref and Natsu who are more dark and destructive in comparison in terms of their abilities and personality as they would again in comparison to Mavis and Lucy the guys would be their darkness to the girls light.
