Sora is a renowned architect famous for a number of buildings across the globe. For a woman who needs to travel so often for work, Sora's career choice ironically clashes with her fear of airplanes. While the world knows about her work and all she's done for the architecture industry, who she is as a person remains a secret. Her fans, her employers, and even those who are close to her are itching to learn more about her. Sora is an enigma, a mystery, who refuses to let anyone know about her scars...until a pilot named Taehyun enters her life. For Sora, he opens not only the sky, but his heart, too.
