She, as the princess, has someone in her heart!
He is a general, his father and brother are alive and dead, and he has a heavy burden on his family and country!
She knew he didn't care about her, so how could she give up without putting out the fire?
He never wanted to keep love in his heart. As long as his elders liked him, he would marry anyone.
Intention: From now on, mountains and rivers will never meet each other, and there is no way to know whether each other is good or bad.
