I think they are good. Why do people hate them? They did nothing wrong. Dont bash them. Their MV is okay they song is good,cute and catchy.

They worked hard to debut. Just because of f(x), alot of people hate them and put negative comment on YouTube. That is mean and unfair. f(x) is f(x) and Red Velvet is Red Velvet.

f(x) stopped promoting early doesn't make that Red Velvet is the cause of this. 

This is a good debut song. What really matter and important is the artist's music not about their company or other group in their companies. People are being too biased over their favourite groups. Be open-minded/

People are thinking too negative and make up some false analysis and blame SM and Red Velvet. We don't know the story behind everything. We are not Kpop idols. Don't try to be a detective when you are not.

I think that a lot of us come to Kpop to relax and enjoy music not because of the dramas and scandals.

GROW UP PEOPLE.
