Loving You Cost My Life

10-year-old Human boy Ethan was rescued by the fairy Mia after being caught in danger in the forest. They grew up together, and Mia settled in the human world with him, secretly bestowing upon Ethan lucky magical powers to help him rise from a career failure to a high-ranking company executive. The price was that she would become mortal and perish if betrayed. However, in his quest for the CEO position, Ethan cut off Mia's wings on their anniversary and presented them to Riley, the CEO's daughter. Severely injured, Mia began a 24-hour countdown to her death. Witnessing Ethan and Riley's intimacy, she was heartbroken and vanished in the rain. Luckily, Mia was rescued by Silas, the forest god who protected her, and reborn in the fairy world. Ethan, however, suffered a career collapse due to the loss of his magical powers. After learning the truth, he regretted his actions and pursued her, only to be met with Mia returning her memories and never acknowledging him again. Thirty years later, Mia and Silas returned to the human world. Ethan, now a disabled old man, saw her happy and passed away with regret.
