What is the central idea of "The Tiger's Whisker"?


Yun Ok spends months trying to win the trust of a dangerous tiger, so she can get one of its whiskers for a potion.


Yun Ok asks the hermit for a potion to give to her husband so he will be loving and gentle the way he used to be.


Yun Ok is worried about her husband after he returns home from the war and wonders if he will ever be loving and gentle again.


Yun Ok learns from the hermit that to win her husband's love again, she must treat her husband the same way she treated the tiger.
