My sister said that Taeyeon doesn't like black-skinned womens, is that true?

It's true that the Korean standard of beauty is a girl with clear white skin. And yes, many don't consider blacks to be that pretty. But it doesn't mean they hate blacks.

If you are referring to the time Taeyeon supposedly said that Alicia Keys was pretty for a black person, then you should should know that antis translated it wrong. She actually said that black person is really pretty :)

Most Koreans don't they just won't say it out loud

I believe that it is absolutely not true at all. Taeyeon really didn't mean it when she said that American R&B singer Alicia Keys was pretty for a black girl. And of course Taeyeon isn't a racist at all

Not true .

i think its not true because all of them except Yuri i mean YUri has The blackpearl skin but Taeyeon is kind ...
