Even Today, the Undercover Agent Is Doted on by the Enemy

You're the school doctor at the police academy, but in reality, you're a mole from the Black Organization. In truth... You've bonded with an undercover System and accept missions from both sides. Fairness is your guiding principle. Of course, that's your secret. Neither side knows. Just as you finish your mission, you fake your death and retire in triumph, living high on the hog at last. Until one day, you're caught up in a hijacking. An old friend from the police academy boards the plane, and your eyes meet. System: Woohoo~ Now this is exciting. You're the school doctor at the technical college, but in reality, you're a mole sent by the curse faction. They entrust you with important duties because of your looks. You stare at the strongest student at the school, lost in thought. Reader's guide: 1. The heroine is an unbeatable Mary Sue, stronger than anyone. At her peak, she's evenly matched with Xin Ling and Mandora. She has a golden finger, and her true form isn't human. Lots of wish fulfillment and over-the-top drama. 2. Written with complete abandon, with heaps of original settings, no logic, and extreme out-of-character behavior. If you feel uncomfortable, click away right away to protect your physical and mental health. 3. The heroine is a good person (A Sang nods). My Brother Keeps Turning into a Demon! After becoming Hell's ten-billionth customer, I won a reincarnation jackpot. A wealthy family, a healthy body, and just one older brother who was supposedly unreliable. If he's unreliable, so be it. I'll reincarnate first and worry about it later. **** **** My family was well off, and I lived a good life. The only problem was that my sole older brother was sickly, and the doctors said he wouldn't live past twenty. Since we were family, I naturally gave him my whole heart, thinking that a life like this wouldn't be so bad. If only he hadn't wanted to eat me. Beneath the moonlight, the boy in ornate clothes who had turned into a demon opened one door after another, his red eyes eerie. "Yueji." "Yueji..." "Where are you hiding?" **** **** The envoy of Hell admitted they'd picked the wrong family for my reincarnation. They promised me this time I'd get two for the price of one, and that I'd be satisfied. Reincarnated once more, I faced two older brothers who looked exactly alike, but decided to trust the envoy of Hell one more time. It wasn't until they joined the Demon Slayer Corps and took the side of the humans that I finally breathed a sigh of relief. That meant they wouldn't eat me, right? A few days later, my eldest brother abandoned the entire family and ran off. When we met again, my eldest brother coldly drew his sword against me, looking every bit like a demon. "I'm done being human, Miyue!" Me: !!! But I still want to be human! **** **** This time, before I could even find out why, I was forcibly sent to another family. One star. I want to leave a one-star review! On my third reincarnation, I stared in thought at my unusual white-haired older brother. He was receiving the adoration of the masses, revered by everyone as a god. If he's a god, surely he won't turn into a... demon? Then one day, I saw my first older brother feeding him blood, and in a flash, he turned into a demon too. ...I'm so done. Theme: We are born free. May courage endure.
