Do you have any good novels about poignant love?

The story went like this: a boy was picked up by a girl's grandfather on a rainy night, and they called each other brother and sister ever since. The boy rarely spoke, but he had deep feelings for the girl. Once, when he returned home, he found that his sister was being bullied by a local gangster. He accidentally killed the little gangster, and thus gained the appreciation of the underworld boss. In order to get rid of the crime of murder and take care of his sister, he accepted the conditions of the underworld boss and joined the gang. Later, many things happened. He and his sister always missed each other. In the end, he helped the police destroy the gang and disappeared in the big explosion. In fact, he did not die. In the end, the two of them, the amnesiac sister, and he were both shot by a sniper. It was a sad story
I didn't explain it very clearly, but that's about it
I hope someone has read this novel and can tell me its name. Thank you.

"I recommend 'An Orphan from a Humble Family: The Escaped Wife of Lord Leng' to you. It's a novel about the heroine escaping from a heartless marriage. She meets a series of men in an unfamiliar time and space, including the physically disabled Underworld Region Lord, the cold and heartless Mo Shang's fate, and so on. The story was full of mixed emotions, the dangers of the escape, and a heartbreaking love story. I hope you like this fairy's recommendation. Muah ~😗
