Martial arts novel master enters

I'm currently writing a martial arts novel. I'm just short of an ending.
When a person was five years old, his sister was killed. Although he loved his sister very much, he was helpless. He felt very guilty and swore to avenge his sister.
After seven years, he met a girl and experienced many things. The two of them fell in love, but just as they were about to get married, the girl suddenly seemed to have changed into a different person. She went against the boy and even threatened to marry another boy. He couldn't take it anymore and finally stabbed her to death. Before she died, the girl took out a jade pendant. The boy was shocked because the jade pendant was left behind by his father when he and his sister were young. The girl was his sister.
The girl told him that she was not dead. Before this, she did not know that he was her brother. It was only two months ago that her master told her the truth. That was why her personality changed during that period of time. It was just to make her brother hate her. Fortunately, when she died, her brother would not be sad because she did not want to be such a hypocrite anymore. The last sentence was
Brother, I'll still be your sister in my next life.
I'm not good at writing either, so I wanted to ask a master writer to help me write about the boy's psychology after he stabbed his sister to death and found out the truth.
Mind you, that boy is cold and withdrawn.
For now, he'll call her Long Tianze. For now, she'll call her Long Qier (sister) and Yun Shayu (lover).
This is my first novel
Help me.
