"Luna, an orphan, was recognized and brought home by the Su family. Yearning for familial love, Luna fulfilled every demand of the Su family without question. Mistakenly believing her parents were poor, she worked tirelessly to support the family, only to be falsely accused of theft and sent to prison. To her shock, Luna later discovered that the Su parents were actually a prestigious noble family in J City, and everything—including her imprisonment—had been a test orchestrated by them to see if her devotion to family was genuine. After her release, Luna, heartbroken by their deceit, saw through their hypocrisy. Yet, the family refused to let her go and staged one final test—this time, with the cruel intention of pressuring her to donate her organs. Years earlier, Luna had been diagnosed with uremia and had only one kidney left. Weak and frail, she refused to donate, but her mother Julia fainted at a banquet and was rushed to the hospital. There, she conspired with doctors to fake hair loss and baldness to manipulate Luna. During the confrontation, Luna’s wig fell off, revealing her severe illness and the suffering she had endured during their ""tests."" Seizing the moment, Luna turned the tables and demanded that the family donate a kidney to save her—but they refused. Finally seeing their true colors, Luna decided to expose them. The Su family, fearing backlash, canceled their final test and planned to announce Luna’s true identity at a shareholders' meeting. However, Luna arrived first and publicly unveiled their hypocrisy. In a desperate attempt to win her forgiveness, the family offered compensation, but Luna scorned their wealth. Her brother Leon, however, proposed allowing her to return to school. Luna agreed. Their adopted daughter Stella, jealous that Luna would attend the same elite school, schemed against her. But Luna, excelling academically, earned her place through merit. Enraged, Stella publicly revealed Luna’s prison past, sparking rumors. Luna seized the opportunity to clear her name and ensured Stella faced consequences. However, Luna suddenly collapsed and was hospitalized. Tests revealed she had little time left. Moved by her plight, Leon decided to donate his kidney. After the successful transplant, Luna recovered and embraced a new life."
