What's Wrong with Being a Little Creepy as an Undercover Agent?

My name is... I've forgotten the name I had in my previous life. In this life, I'm Asano Kiyoo, codename Bailey's. I'm currently undercover at the Tokyo Metropolitan Police Academy, and doing a fantastic job of it. This is a precious assignment I earned by punching Gin and kicking Pinga. The reason is... In my previous life, I was a self-insert fangirl for the heartthrob who held 12 million hostages. Since I was a fangirl, it was only natural to collect photos of my fave and the handkerchiefs he'd used, and sneak into his dorm at night to admire him while he slept, right? I'm not a creep, and I'm definitely not an idiot. I always wore a good disguise when I did those things, and I was very careful to keep my real self at a distance from him. Especially when he approached me, I always kept well away, so that even if he realized he was being watched, he wouldn't know I was the one watching him. At graduation, his childhood friend suddenly shoved him in front of me. He asked, "Are you coming to the graduation party?" A police party? I wouldn't go if you paid me. "...Do you hate me that much?" Making Matsuda think I hated him was exactly my strategy. That way, he was even less likely to think I was the person spying on him. After graduation, I became a Public Security police officer. I kept up the same strategy: my real self stayed at a distance, while my disguised self enjoyed my fave. But that wonderful life ended when my identity was exposed and I had to make an emergency escape. I was back at my apartment, clearing away any trace of myself, when I ran into my fave and his childhood friend. My fave was holding a scrapbook I'd made with my own hands: "Records of My Love for Matsuda." I'd been exposed. ...I can't go on living. I didn't dare look at the disgust on his face. "Why did you do this? Why did it have to be you...?" His voice had never sounded so hoarse and pained. I was the one responsible for all of this. I had watched him, desired him, and betrayed him. He probably thought I was disgusting. He probably never wanted to see me again. I'd do as he wished. A staged death, and Asano Kiyoo disappeared from this world. I changed my appearance and showed up again, but I couldn't help getting close to him. It was fine. As long as he didn't find out, I wasn't breaking my word. And if he did find out and catch me, then what? I'm shaking right now, with no idea how this man plans to punish me! As expected of Matsuda, he lowered his eyes and kissed me. It even looked like he planned to sleep with me. I had to remind him. "You might not know this, but I really, really like you. This isn't going to punish me." His expression immediately darkened. "I'll just enjoy it." Matsuda looked like he was getting furious, his face turning red. When I felt him start to pull away, I hurriedly hugged him again. I didn't want to miss what might be my one and only chance. "Actually, if you just stopped holding back, it could count as punishment." "Let's do it once. After that, I promise I won't like you or bother you anymore." This suggestion of mine had to be considerate. At last, he gave me a gritted-teeth smile. [Notes] 1.
