Interview with Cube via x-clusive.sg

So it is Doojoon who whistled for Trouble Maker. I saw a convo on weibo and asked my friend to translate it for me.

They were saying, “Now I finally know who is the one whistling for TM.”

And they replied to each other talking about Dujun practising for the whole day and ended up coughing so badly but he kept whistling. Something like that. 

Can’t screencap cause it’s a personal convo between ‘em >.< Let’s wait for news article to confirm it! \O/ 

It was mentioned during their recording for Win Win ^^
