He continued, "There was a kiss in the scene where my sister appears. How could I have skinship in front of a family member? I didn\'t think it was right, so it was hard. I filmed it while shivering." 

You can check out the full MV of Thunder\'s "Sign" on December 7. 

he should have just kissed Dara , it would have left more impact , also I think it would be kind cute to break the taboo .

Dara might be crying inside since her baby brother is all grown up now hehehehee :3

Hope there are B cuts or behind the scene footage... maybe Dara yelling at him for not doing it properly or something XP
