Well, there's this "Real Sound" Documentary featuring Taeyang and his behind the scenes preparing for his solo comeback with "SOLAR".
Dara is part of the music video as well as G-Dragon. In the recent video's revealing a part of "Real Sound", Dara was interviewed, and just by the intro, you could see Taeyang "Comfortably" introduced her to the camera.
The whole "dara cut" shows the two of them describing their relationship (pretty cute, made me scream a couple of times) even if they have known each other for 5 years, they still get awkward with each other!
and by the end part... he expressed his sadness that Dara likes "flower boys" and kept on saying that "I probably wont do" in which Dara quickly evades the whole thing and They left the scene.
Look's like they are pretty cloes huh? >=)
