When single mom Diana starts working as an air traffic controller, she hears her ex-boyfriend Anthony’s voice over the radio. Since Diana broke up with him for the sake of his captain dreams, she’s grateful her sacrifice wasn’t in vain, and keeps hiding that he’s the father of her daughter. But she doesn’t know Anthony is actually the new billionaire CEO of their airline!
Leah, the daughter of the chairman of CloudSky Airlines, had always dreamed of becoming a pilot. In high school, she fell in love with Harvey and chose to abandon her aspirations to become an air traffic controller for him. Seven years into their marriage, she waited in the control room for his return, only to discover his ambiguous relationship with flight attendant Sheila, leading to their divorce. By then, Leah had been diagnosed with stomach cancer. To ensure Harvey's flying safety, she decided to forgo treatment and continued working. When he confronted her about neglecting her health, Leah realized she could no longer sacrifice herself for someone who didn’t value her. She chose to divorce Harvey. After Leah left, Harvey felt the void in his life without her care. He longed for her return, but she was already building a new life.
