There's actually some hate going around One Direction/ fans and Babies about One direction's mv for the Best Song Ever. According to my sister, who is a Baby, fans of Bap are arguing and hate-ranting about why One Direction crop Zelo in the group picture and why One Direction tore the picture into pieces. Okay, let me get this straight, I am both directioner and baby in a way.

1st. Why Zelo has been cropped in the group picture.

Zelo has been cropped in the picture because One Direction consists of 5 members. BAP has six members. In the MV, Geek Harry is introducing new costume concepts to One Direction. The new costume concepts have been done by popular groups like Backstreet boys and the like, and Harry is introducing them to One Direction, by putting faces of One DIrection on each of the members. Bap is also included on the introduction-- their concept being in jumpersuits and being all blonde. The faces are also edited, meaning 1D's faces are placed on top of Bap's faces. 

I think the reason is perfectly legible. You can't put Zelo because it will become six, and not the needed five members. What they needed was the concept! Introducing new costume concepts by putting 1D's faces served as a parody of some sort. In hindsight, I think we should be glad because this is like an acknowledgment somehow. Bap being in the MV with the known groups is like saying BAP is known internationally, and by bigstars like One Direction or anyone in UK, really. 

2nd Why One Direction tore the picture into pieces,

Neither it was meant as an attack to Bap, nor it was to say that One Direction hated Bap, geez. In the MV, the management is like insisting them to try new/popular things that are clearly not for them. They tore the pictures of the concepts NOT JUST BAP's, but all of the picture concepts. It's a retaliation that is supposed to say, This is not us! and in the end of the MV, they have this big picture of them just smiling and being normal and simple with a written sentence, "THIS IS US!"  Different aims, different reasons, guys.

Let's just stop hating, guys. Babies, Directioners or whatever.
