You're Wooyoung, the ballet dancer. San performs in the same theater as you and is also a ballet dancer. One evening, while Wooyoung was practicing Odette's dance part from the White Adagio alone, the door of the dance hall opened quietly and he heard the voice of another dancer.

It's the women's part. Why are you dancing it?

It was San. And his role in Swan Lake was that of Siegfried.
