I don't think there is anything special about red hair. It's all because of the company, and girlhood and fx.
Although red velvet is a female group launched by SM, its strength is a little different from that of girlfriends from small companies.
I didn't mean to hate red hair. I look at it from an equal angle. The core monument of life, my girl group, used to be a teenager, but because Sika quit, she didn't pay much attention. Now the core monument of life is a bottle.
