About the Song
《KNOCK KNOCK》 is a bright and charming single by South Korean girl group TWICE, released on February 20, 2017, as the lead track of their special album TWICEcoaster : LANE 2 through JYP Entertainment. Written by Shim Eun-ji, Collapsedone, and Mayu Wakisaka, the song builds on the playful narrative introduced in “TT,” using the sound of knocking as a metaphor for opening one’s heart to love. Ahead of its release, anticipation grew with two teaser videos unveiled on February 17 and 18, followed by a final group image teaser and a live comeback countdown on Naver V Live, culminating in the official music video and digital release alongside the album, marking 《KNOCK KNOCK》 as a key moment in TWICE’s continued rise in 2017.
