As of right now (1:45AM KST), there is no word on the state of the music video for 붙잠았어야 해. However, there has been a music video filmed as reports by various news outlets (Naver, Soompi, etc.). It is likely that, due to a change in chart ranking rules, the music video will be released today at noon KST. As there as updates, we will continue to post information.
Edit: The new ranking rules only count music videos uploaded(?) between noon and 6PM KST. This does not technically go into effect until February 27, but Fantagio may have chosen to take action upon it now.
