The website make a mark East sea to Sea of Japan. And their reaction is terrible.
In the same case, Netfilx, they did same mistake, and Korean claim that it is not true. And they amended their subtitles.
As a world citizen, we have responsible for correcting wrong information, and accept it.
However the website don't have receptive attitude. It deserves criticism, of course.
They have to correct the mark as soon as possible.
