She died for the male lead. Were the female lead and the male lead together?

I'm looking for a novel. At first, the female lead approached the male lead because she was jealous of her sister. The second male lead liked the male lead. In the end, the second male lead was killed by a car because he gave the helmet to the female lead. The male lead doted on the female lead. The female lead was very young. There was a plot where the female protagonist was chatting with a beggar by the roadside. The above is a novel that I read a long time ago. I want the name of the novel. I hope you know the name of the novel ~ Crab crab ~
