I’m aware of other popular pairings like Haesica, Yoonhae and Sifany. But I just can’t help it and ship Haefany. Because..

1. They look so good together
2. I actually like Tiffany.. she’s like an Angel
3. They have a lot of things in common
4. The fact that they are close friends

Now let me compile all the Haefany moments that I know of:

• They were together (not the whole time tho, but still) at SM Town LA ‘10’s back stage.
• At GDA ‘09, I spotted Donghae held Tiffany’s hand for a while. On stage.
• At SM Town Bangkok ‘08, they interacted and then walked together with Donghae holding Fany’s arm very lightly. 
• SM Town ‘09 was the best. Donghae can’t stop playing with Tiffany. Donghae poured water all over Tiffany in Bangkok, and some time later Tiffany grabbed Donghae’s wrist for being such a tease.
• “If Tiffany is here, when I call her, she will be like ‘Yes, oppa?! Yeah, oppa?!’” — Donghae often question why Tiffany always eager and excited whenever Donghae call her.
• During the making of Kissing You music video, you’ll see the way Donghae looked at Tiffany talking to the camera. It was precious.
• And, recently their love shine during the concert of SMTown in Paris (Video link)

Yeah. I’m shipping this couple more than I should. More than I ship myself with him. True fact.
