Okay, so I guess I should start off with saying that netizens have known about this couple for quite a well. I've seen several Pann posts about it but a lot of fans from each side dismissed it as coincidence at first (like cryptic messages on their mini-homepages to each other) so I didn't think much about it either.
Anyway, most of Korea is sleeping atm so the vote numbers are pretty low.

1. [+148, -14] I know Eunhyuk's facial expression very well. It's the expression men feel after sweating from doing 'something' and it's the physical exhaustion that follows.
2. [+140, -16] They did it... They did it...
3. [+132, -34] And here she was trying to push for the innocent nation's little sister image ㅋㅋㅋ There was a reason people called her a sly fox.. ㅋㅋ I knew from the minute she kept changing her ideal man that there was something fishy. I bet IU and Super Junior fans are in total mental breakdown right now... She's a young female celebrity barely 20 years old that's sustaining her career through the love of her uncle fans... and she's already rolling in the beds of male idols~ Will IU's agency claim that her Twitter was hacked, or photoshopped, or what next..? ㅋㅋㅋ
4. [+53, -4] Jiyeon: We're best friends ㅋ
5. [+46, -1] Of all the pictures to accidentally upload, it had to be a bed selca basically broadcasting to the world that they had sex
6. [+46, -8] Goodbye IU
7. [+42, -4] Jiyeon: Definitely my friend ♥
8. [+41, -2] The only way they can salvage their careers is if Eunhyuk comes out tomorrow and honestly confesses, "Yes, we had sex... Can't consenting adults have sex?"
9. [+40, -3] Honestly, though, I know that IU is lovely but isn't it obvious that she's a fox? ㅋㅋ She doesn't look all that innocent so where's all this shock coming from
10. [+36, -3] You sly fox....... look at his eyes all dazed out

1. [+36, -3] They're adults so it's possible but... Pajamas and Eunhyuk's topless... Jieun, what are you going to do... You can't even deny this if you tried... This uncle can't sleep..
2. [+38, -6] ㅋㅋㅋ If you look at a bigger size of the picture with Eunhyuk, you can see that they're on a white couch. It's the same couch that was in Eunhyuk's house shown on Star Life Theater ㅋㅋㅋㅋ Bye bye IU
3. [+33, -4] Lee Yong Dae: Jieun, thank you!!!! (TN: Lee Yong Dae is an athlete involved in his own scandal over his new girlfriend)

1. [+68, -3] Go Young Wook "Our Eunhyuk is not bad himself? Chwahaha"
2. [+59, -5] We have no problems with pictures of dating coming up. No problem with a couple picture taken outside somewhere. But a picture taken together on a bed topless is basically sex. This is how the two have catapulted their careers into the ground ㅋㅋㅋ IU's nickname has gone from Nation's Little Sister to Nation's Porno Sister ㅋㅋ
3. [+55, -12] And is this how IU's career crashes and burns? I recognize that the journalist is adding to the fire but she really can't deny this given the evidence here...

1. [+29, -2] I'm pretty sure she proved something else other than her waist today....
2. [+32, -12] You fu*king bi*ch why did you have to go and do that I really liked you tsk tsk. I'm not saying that dating's bad, but did you have to prove it like that, you empty headed bi*ch
3. [+9, -1] Yup, she proved it all right
