Having revealed a bunch of concept photos for their comeback earlier in the week through their official website, it would appear that either it was a marketing strategy or a big mistake in leaking them as the website has now been locked down again with a cryptic codebox. Visitors to the website previously were able to key in any code and thereafter be presented with their 11 concept photos. But it won't work now and there is now a hint at the bottom saying, "hit your heart," leaving fans baffled. But of course, netizens will find a way and they write that by keying in "h-u-h", there will be a pop-up yielding a high quality concept photo which can be used as a desktop wallpaper. Previously. Now. So stay tuned on allkpop for the MV teaser of their title track Huh/Hit Your Heart on the 17th. The album will be released on the 19th while on the following day, 4minute will have their first comeback stage through M! Countdown.
