The first time they met after rebirth, he gave her a murder weapon
The second time they met, he tortured her to death
The third time they met, he was covered in blood and agreed to meet on the battlefield.
He saw her crying, he saw her resolute, he saw her putting aside her personal grudges and fearlessly protecting her country and family.
From being indifferent to the world to just wanting to stay in the world with her, in this life, she never wants to leave his side again
