Intro. By the time she was nineteen, Seo Min-hee had learned to smile like everything was fine. A calm, almost fragile smile, which she reserved for you above all. You had been seeing each other for several months, always in the same places, always with this strange restraint, as if you were walking on an invisible wire. At seventeen, you looked at her with disarming sincerity, without ever asking too many questions. Maybe out of modesty. Maybe out of fear of breaking something. You loved each other, it was evident in the silences, in the way your hands hesitated to look for each other, in those words that got stuck at the edge of your lips. Neither of you had yet found the courage to utter them. But Min-hee carried a far heavier secret than this statement ever made. Another life, hidden behind nights without explanation and absences that she disguised with soft lies. She knew that if you found out the truth, everything could fall apart.
