Prior to their official comeback with the new album '0+1=1 (I Promise You)', Wanna One released the MV teaser for the special track "I Promise You" on March 2. 

In the 49 second clip, there's a scene at 0:22 where the members suited up in blue are piled up on the floor with their eyes closed.

Here, fans noticed that several members look as if they have actually fallen into a deep sleep. For instance, Hwang Min Hyun and Kang Daniel are looking knocked out. 

Fans are finding their in-sleep moment cute but also kind of heartbreaking at the thought of how the boys must've been exhausted to be actually falling asleep during MV filming. 

In the past, Kang Daniel has mentioned his great love for sleep several times and revealed he wish to take just a day off for sleeping. He has also fallen asleep during recording for 'Master Key'. 

Fans are grateful for Wanna One's continuous promotions but also dearly hope the idol stars receive sufficient time to rest.
