I didn't know that another huge band was accused of plagiarising Day6

Uh-oh. When did this happen?

Their name sounds familiar

I think these lyrics videos are made by one company hahah but I could be wrong.

Not particularly this but I’ve seen many similar looking lyrics videos

Possibly inspiration, day6 released their video a month before Arashi, in the beginning it seemed similar but towards the middle it was different. Not sure if this real or not but the video director said this about the issue:

Director A, who produced the music video for Day6's'Zombie' Lyric, responded by saying, "I should call this an honor. It's a video I made with real affection" through his Instagram story.

In an interview with the media, Mr. A also said, "I understand that it is an era where 100% pure creation cannot be made, but it is true that I am upset." He said, "We made it well and we have even copied Japanese national idols." “I also expressed my regret.

So I guess he is taking it with a grain of salt. Also your right Arashi's song is real good.

oh yeah, of course, japan national idol group and best-selling BG in asian history need to copy a kpop nugu group haha
