Why are people so obsessed with couples?

Ok. Fairy tail, is an ACTION ANIME. It may have some teeny bits about romance and all that, but it's basically all about butt-kicking, fighting, and all that awesomeness. Why is everyone going so crazy about couples? For example, the NaLu and NaLi fans. Everywhere I go, people are swearing, arguing, etc. like stop! Who cares who natsu ends up with? I mean sure, even I have some couples I ship. But there's no need to go crazy if someone thinks differently. I mean, what if the লেখক decides Gray, অথবা Natsu, অথবা Erza ends up with no one? Then who are আপনি gonna scream at? The author?? -.- it's been really annoying cause lots of characters have been getting hate just cause people want different pairings. If natsu ends up with Lisanna, he ends up with Lisanna. If gray ends up with ultear, he ends up with ultear. আপনি can't do ANYTHING about it. So আপনি might as well stop this pointless arguing, cause its getting on my nerves. Go watch naruto. At least in that, there isn't much romance in there, and no one gives two shits who ends up with who. Not that I'm saying fairy tail sucks অথবা anything. (cause it doesn't. It's awesome) Honestly though, if your here just for the romance, then go watch Mew mew power, shugo chara, whatever. This is জীবন্ত for the action lovers. The people who wanna see some real fighting. And someone please explain to me the reason why everyone is obsessed with couples, and pairings? Thanks!
