I ship TAMAHARU with a burning passion. They look so cute together! But, you see, there are also those little unappreciated ships like MoriHaru and KaoHaru that DESERVE some love too!
Tamaharu is OBVIOUSLY Canon. They fall in love, get married, tango between the sheets have kids, blah blah blah. And I know that Mori and Hunny probably only thought of her like a sister. So, why do they get shipped? Because Mori's hot Because of resistent fangirls. They thought that maybe Tamaki would be like, "OMG Haruhi is soo cute" but then dies of kawaiiness or dies in some way or he gives up on her or whatever. When that DOESN'T happen, there's a canon vs. non-canon war.
If the fangirls who DISLIKE the canon or disagree with it or something, then the other fangirls are like, "It's canon! You HAVE to ship it!". And sometimes the anti-canon fangirls disagree and write fanfictions where Tamaki is some idiotic or stupid idiot and loses Haruhi to Kyoya/Mori/Hikaru/Kaoru/Hunny?/Shiro/Renge. And you really can't side like this.
This is the story of the dreaded Canon vs. Non-Canon wars. If you are dumb enough to watch Ouran and be clueless then enroll in my Message Board.
