- I.O.I debuted on 1 April 2016. 11 members were voted by viewers on the music survival show Produce 101 (2016).
- Producer Ryan Jhun (known for Red Velvet’s “Dumb Dumb”, SHINee’s “View”, etc.) labels this song’s genre as “trapical dutch funk”.
- This is actually the second revision of the music video. It is unknown why it was reedited, but some speculate that fans were unhappy with how hyper Yeon Jung was in the first video, taking the spotlight from Somi, who is supposed to be the group’s center.
- Na Young was voted leader of the group by the members. During Produce 101, she was nicknamed “Stone Buddha Na Young” for always being so expressionless.
- Chunga Ha doesn’t like to put on make up, especially since she knows she’ll be edited out anyway. Little did she know, this is not always the case. See also 0:58 in the music video.
