My only concern is that since there WERE like 19 covers for this single (give or take) the sales are just a product of the hardcore fans buying 2 or 3 different copies, versus new casual fans being in on the 100k first week sales- ya know?
None of you can prove anything one way or another, and all this is going to result in is a lot of butthurt, so instead of all of this needless back-and-forth, let's instead just chill.
Have we seen a dance for Seishun Domannaka yet? It sounds like the dance could be FRIGHTENINGLY ADORABLE.
