She was poured into a state of forgetfulness by her enemy, and she no longer had any emotions, so she willingly married him.
There was another person in his heart, and he hated her. He treats her badly, but she always laughs it off.
He was confused, he was angry, and he was paranoid about hurting her. But he later discovered that he actually felt sorry for her.
She accepted her fate and swallowed all the bitterness in her stomach. She still smiled at him, but her heart became empty when she faced him.
Finally, in front of his childhood sweetheart, she made an understanding and inserted the sword into her chest.
They missed each other, but you know, the end means a new beginning.
