Can someone help?

I remember the first book my sister read was called 'Angel Street Corner' (have you read it? Help me think of the correct name). This book tells a tragic story. The male protagonist is named Ye Mingyao, and the female lead (I don't remember). They are a sibling pair who originally had a complete family, but later their father died, and their mother was forced to their death (the mother was forced to do something to her because someone tried to force her daughter to do her). The older brother was hit by a car and was downcast. The car owner had no sons and adopted the older brother, while the younger sister was adopted by someone else. They only met in high school. When did the older brother have a girlfriend, and because she promised her adoptive father not to tell her brother his identity, she was fiercely pursued by him. However, later the sister got a boyfriend (with many boring little stories in between), but during a gangster skirmish, she lost her virginity for her boyfriend. But the sister's boyfriend thinks another girl saved him, and to repay the debt, she leaves his sister and starts dating that person. In the end, when he discovers that the real person who saved him is his sister, she has already been in a car accident, and at the same time, her brother (Ye Mingyao) remembers his identity. He keeps repenting in front of his sister. Before dying, the sister only says to her boyfriend, "I love you" (I think the name of this book is wrong; if anyone has read it, help think of what the title is.) )
