I had been in love with Su Qing for three years. She was the most perfect light in my life. Until I found a microSD card hidden inside the lipstick tube she had left behind. It contained a recording of her talking with a man codenamed "Professor" about how to extract data on a new type of fuel from me, a core engineer at an aerospace research institute. In her gentle voice, she said the coldest words: "Don't worry. He loves me with all his heart. He'll never suspect a thing." That night, I didn't confront her. I wiped away my tears and opened an encrypted number on my phone that I'd never contacted before. "Hello. I'd like to activate Operation Homecoming."
