I walked into the internet cafe's restroom, locked the door behind me, and let out a loud fart. My stomach felt much better afterward.

  As I looked around, I noticed that someone had written "Beautiful Girl Overnight" on the door with a black marker, followed by a phone number.

  I was taken aback for a moment before realizing that this must be an advertisement left by a prostitute from a red-light district.

  It's amazing how far these ads can reach - even into the restrooms of internet cafes!

  As I stood there, I began to let my imagination run wild, and all sorts of scenarios started playing out in my mind. My body started to react accordingly, and I felt myself getting aroused.

  I tried to suppress these thoughts, but the more I tried to push them away, the more vivid they became. My breathing quickened, and I felt a sense of tension building up inside me.

  I'm not sure if it was the words "Beautiful Girl Overnight" or the phone number that triggered this reaction in me, but I couldn't shake off the feeling that I was being incredibly depraved.

  I've always thought of myself as a decent person, even if I wasn't exactly a paragon of virtue. But now, I felt like I had sunk to a new low.

  As I stood there, I started thinking about my past relationships. There were only two girls I had ever been with - one was Gu Xue Lin, and the other was a girl I met while working as an editor at a magazine.

  We only dated for a month before breaking up due to our differences in food preferences. She liked to add vinegar to her noodles, while I preferred to add scallions. It seemed like a silly reason for a breakup at the time, but looking back, I realized that it was because I didn't want to accompany her on outings and activities.

  Later on, when Gu Xue Lin came to visit me during the National Day holiday, I made sure to take her to all the places she wanted to go. We had a great time together, and eventually ended up living together.

  As I stood in that restroom, staring at the words "Beautiful Girl Overnight" on the door, I felt like I was betraying Gu Xue Lin's trust and care for me. It was as if I was insulting her and our relationship.

  My mind was a jumble of conflicting thoughts - one part of me was screaming at myself to stop being so depraved, while another part was tempting me to give in to my desires.

  In the end, I found myself dialing the phone number on the door. My heart was racing as I waited for someone to pick up.

  The phone rang twice before going unanswered. Maybe it was just a prank call?

  I decided to hang up and cancel the call. As I did, I felt a wave of relief wash over me.

  But then my phone suddenly vibrated in my hand, and I saw that Gu Xue Lin was calling me. My heart skipped a beat as I answered the call.

  "Hey, are you okay? You've been gone for over 20 minutes," she said.

  "Yeah, I'm fine. I'll be right back," I replied.

  Gu Xue Lin hung up, and I quickly washed my hands before exiting the restroom.
