JYP completely fails to give Twice B-side music videos. When looking at this chart
You can see Twice is in a division with a lot of staff. It only contains JYP and VCHA. JYP rarely comeback and VCHA hasn’t even debuted yet so basically most of their focus is on Twice. Now I’m not saying Twice is neglected in all areas. However, in making MVs outside of their title track they definitely are. I don’t know how accurate these numbers are but here ya go
As you can see every other JYP group gets it. That isn’t a bad thing however it just highlights how Twice lacks b-side MVs in comparison. Twice literally built JYP to what it is today along with Got7 and to a smaller extent Day6. Twice being the only active group from the three deserves to be given an every b-side MV for their album but honestly I think fans would take 1 or 2 more besides the Title track.
