This one is okay, can you really see it? The heroine is becoming more and more possessive, but she doesn't know if she will turn into a yandere later on.
The ventilation ducts were full of dust and the smell of rust. I crawled forward, and the whiplash on my back was rubbed against the rough pipe wall, which was painful. Every time you climb, you have to stop and hold your breath to listen for sound - Su Wan's footsteps are like tarsal maggots, looming outside the pipe. "Come out..." Her voice came through the metal, with a strange tenderness, but it was more creepy than a scream, "You can't run away, I am familiar with every inch of this place." I didn't dare to respond, gritted my teeth and continued to move forward until I found a fork, turned in suddenly, and huddled in the corner. The footsteps outside the pipe stopped at the same position just now, as if they were judging my direction. Cold sweat slid down his forehead and dripped on his dusty hands. I don't know how long it took, but the footsteps gradually faded away. I breathed a sigh of relief, and just when I was about to take a breath, I heard a "click" and the fence above my head was lifted. Su Wan's face appeared above, her eyes as cold as ice: "I found you." My heart stopped and I turned around and crawled deeper into the pipe. She leaned half of her body in, and at some point there was a sharpened steel bar in her hand, shining with cold light. "Don't make me do it." "You're crazy!" I roared, rushing forward on my hands and feet. The tunnel was so narrow that I couldn't turn back. "You forced me!" Her voice was crying, but even more crazy. The steel bar stabbed over, grazing my ankle and bringing up a string of blood beads. I staggered and endured the severe pain as I crawled into the narrower branch. There is only room for one person to crawl here, so she can't come in for the time being. I could hear her kicking the pipe outside, making a dull sound, and kept mumbling: "If you break your leg, you won't run away... I will take good care of you and never let you suffer again..." Fear wrapped around her heart like a vine. I knew she wasn't joking, she really planned to keep me forever in this way. When he emerged from another vent, he had reached the fire exit of the apartment. I stood up holding on to the wall. The wounds on my back and scratches on my ankles made me almost unsteady. Just as I was about to run down, there was a sudden noise from the corner of the stairs. Su Wan was standing there, still holding the steel bar in her hand, her hair was messy, but her eyes were unusually calm, terrifyingly calm. "There's no place to run." I turned around and ran up. Every step involved my wound, and the pain made my eyes black. Her footsteps followed closely behind her, getting closer and closer. "Bang!" The steel bar hit the wall I had just supported, splashing a piece of cement debris. I was so frightened that I slipped, rolled down the steps, and hit the platform hard. Su Wan caught up with me, looked at me condescendingly, and raised the steel bar. "I won't let you run away this time." I looked at the gleaming steel bar and knew she was really going to break my leg. The survival instinct made me burst out with the last bit of strength, and I rushed over, hugged her leg and pushed her hard. Su Wan lost her footing and fell on the steps. The steel bar fell out of her hands and rolled down. Ignoring the pain, I got up and ran down. I rushed out of the fire escape and into the corridor of the apartment building. It was already dark outside, and the voice-activated lights in the corridor were brightened by the sound of footsteps, and then turned off in the silence. I rushed into the safe passage and ran down as hard as I could, my own breathing and heartbeat filling my ears. When I ran to the third floor, I suddenly heard Su Wan's voice coming from downstairs. She seemed to be calling my name, with an almost desperate pleading in her voice. I paused, but I immediately realized that it was a trap. I turned into the corridor on the third floor, opened an unlocked door and hid in. It was an empty apartment, the furniture covered with white cloth. I leaned against the door, shaking all over, and the wounds on my back were soaked through my clothes. The moonlight outside the window shines in, reflecting the blood stains on the ground, which are traces of my escape. Suddenly, the phone vibrated in my pocket - it was a system prompt: [Maintenance is about to end, countdown to 10 seconds...] My eyes suddenly lit up and I tightened my grip on the phone. 9, 8, 7... The sound of a key being inserted into the keyhole came from outside the door, and Su Wan's figure appeared at the door, holding another steel bar in her hand with a determined smile on her face. 3, 2, 1... [System maintenance is over and functions are restored. The familiar feeling of strength suddenly surged through the body, and the pain in the back suddenly alleviated. I watched Su Wan rushing over holding the steel bar, and my eyes turned cold. The moment her steel bar was about to fall, I stepped aside and raised my hand to grab her wrist. She was very strong, but she was vulnerable to my restored strength. "You..." Su Wan was stunned, a trace of panic flashed in her eyes. I didn't say anything, I just looked at her, the paranoia, madness, and deep-seated fear in her eyes. Finally, I let go and turned toward the window. "Don't look for me again." After saying that, I jumped out of the window and disappeared into the night. Behind him, Su Wan's heartbreaking cry could be heard, as well as the sound of something being smashed. But I didn't look back - there are some prisons, once you break free, you should never go back.
