It's an old Korean movie, I'm asking for the title

A pair of siblings, not related by blood, came to Korea (if I remember correctly) and they loved each other. The older brother worked hard for his younger sister and later joined the underworld to support his younger sister's college education. The older brother was arrested for a criminal offense, and the younger sister was not saved. The older brother agreed to marry the son of the prosecutor. Her brother was wearing sunglasses at the wedding, and his heart ached. Later, the prosecutor's son found out that they were not biological siblings and abused his sister. The sister resisted and killed the prosecutor's son by mistake. The brother came to pick up the sister and took the crime of murder. They met before her brother's execution! In the end, her brother died! The film was very touching. I only described the general plot, hoping that someone could tell me. Thank you very much!
A pair of siblings. They were not related by blood. The younger sister was adopted by her father when she was young. The younger sister was raped in middle school, and the older brother paid the younger sister. Later, because he was unwilling to tell the police that the younger sister was raped, he was sent to juvenile prison. After they were released from prison, the two came to Seoul to make a living. They loved each other and lived together, but they never had sex. The older brother worked hard for his sister. When he was working at the construction site, the underworld came to cause trouble and was subdued by the older brother. Later, the older brother joined the underworld and became a small leader because he was very good at fighting. He supported his sister to go to college and bought a house for her, but he did not marry her. He felt that his sister should not marry the underworld. The older brother was arrested for a criminal offense, and the younger sister agreed to marry the son of the prosecutor who had been wooing her to save the older brother. Her brother wore sunglasses to attend the wedding. Although he tried his best to hold back his heartache, he still could not hold back his tears. Later, the prosecutor's son found out that they were not biological siblings, and that his sister did not love him. He often abused his sister. His brother begged him to treat his sister well, but he failed. Once again, he abused his sister and accidentally killed the inspector's son with a sharp weapon beside her. His brother came to pick up his sister and took the crime of murder. They met before her brother's execution! In the end, her brother died! However, the elder brother left behind a child (the name was a word for each of the siblings). The child was born after the younger sister got married. The child's mother had already died. At the end of the movie, the younger sister came to the child's side. The film was very touching, especially the part about the wedding and the meeting before the execution. It made people cry! It stated that the film was at least 3 or 4 years ago, not a brother and sister, not a XX movie
