Actually my OTP is Eunhae.
That doesn't mean Kyuhae isn't.
It's just Donghae is my bias and Hyukjae being the second and Kyuhyun the third so naturally I would choose Eunhae over Kyuhae.
The reasons why I chose Kyuhae to write fanfic is
1. Eunhae already has loads of writers while Kyuhae only has...5?
2. I read loads of Eunhae/Haehyuk fanfics so many of my imaginary Hae and Hyuk are influenced by those awesome writers.
3. Kyuhae always appears in my writer's world. They are the pair for me to place as the uke and the seme.
4. I just love Kyuhae.
5. And
cablackwood love Kyuhae. (If this has anything to do.xD)
So I hope it makes sense why I write Kyuhae and constantly spazz over Eunhae.
And I ONLY write KYUHAE. Please don't ask me to write other couples, even Eunhae. I can't. My imaginary world only revolves around Kyuhae. ^_^
