It soared past IU’s “Twenty-three” which has been firmly grabbing the top spot after its release on Friday.

The track also topped China’s Baidu King’s chart, with other tracks also ranking high.

The lead track “4 Walls” is an electronic dance music, depicting the confusing emotion due to the sudden love that one faces.

The quartet will return to the music scene beginning with Mnet’s “M! Countdown” on Thursday, followed by KBS‘ “Music Bank” and MBC’s “Show! Music Core” on Friday and Saturday, respectively.
