I notice IVE'S MV teaser "After Like "is the same day with blackpink comeback...

It must be a coincidence but I don't think it will affect the groups? Releasing the MV on the same day might have been controversial if you mean the views, but the teaser is nothing. Those who plan to watch BP's MV will watch it and those who plan to watch IVE's teaser will watch the teaser.

I'm a fan of both so I'll watch both
