“Actually, I’m quite interested in the scar on Manager Han’s back.” Wang Shen stood up from the sofa. “Manager Han, would you mind if I went to the balcony to take a look?” Wang Shen asked, pointing to the balcony not far away.

Han Lin was stunned for a moment, then looked at Wang Shen and nodded helplessly.

Wang Shen walked to the balcony, looked at the floor-to-ceiling windows, turned to Han Lin and asked, "Manager Han, you said the scar on your back was from being scratched by glass during the renovation. Such a big scar must have come from a very large piece of glass." As Wang Shen spoke, he touched the floor-to-ceiling window beside him.

"Is it this glass window?" Wang Shen asked, pointing to the floor-to-ceiling window in front of him.

Han Lin looked up at Wang Shen, his eyes filled with complex emotions. Wang Shen's train of thought was so abrupt that Han Lin couldn't keep up for a moment and could only nod helplessly.

Wang Shen smiled at Han Lin, "As far as I know, the neighborhood where Manager Han lives isn't cheap. The glass used in your home must be the best quality, right?"

"It'll do, it'll do," Han Lin stammered as he looked at Wang Shen.

“I think the glass in these windows is all tempered. For safety reasons, even ordinary households wouldn’t use ordinary glass when renovating. Manager Han, do you agree with me?” Wang Shen left the balcony and sat back down on the sofa, staring at the dejected Han Lin.

“That’s right,” Han Lin replied.

"That's very strange. Since it's tempered glass, even if it breaks, it shouldn't leave such a big scar, right?" Every word Wang Shen said was a trap, leading Han Lin step by step into it, and then closing in to capture and kill him.

After listening to Wang Shen's words, Han Lin's mind raced for a moment, and he suddenly realized the fatal flaw in his reasoning. Han Lin avoided Wang Shen's gaze, unable to find a reason to refute him.

"Of course, someone as busy as Manager Han can't possibly supervise the renovation process all the time. It's possible the workers used inferior materials, substituting non-tempered glass for tempered glass. Manager Han, you've probably been fooled, otherwise how could you have gotten injured?" Wang Shen smiled at Han Lin.

"Yes, yes, that must be it. I'll go talk to their boss when I have some free time in a couple of days." Han Lin quickly wiped the fine beads of sweat from his forehead and explained, following Wang Shen's words.

Wang Shen nodded, picked up the teacup on the table, and took a sip. Halfway through his drink, he suddenly looked up at Han Lin and smiled. "Manager Han, something else just suddenly came to mind."

"Something else?" Han Lin rolled his eyes. In his panicked state, he had no idea what Wang Shen was thinking.

"Yes, it's a recent case. It's also a murder case. The murderer is a woman, and she's quite pitiful. This murderer fell in love with her boss since college, but unfortunately, her boss didn't love her at all. Because her boss already had someone else in his heart. Manager Han, who could it be that her boss loves?" Wang Shen paused halfway through his sentence, holding a teacup in his hand, and looked at Han Lin to ask.

"How would I know that?" Han Lin replied casually.

"You also know the person her boss loves, it's Han Mo," Wang Shen said slowly after taking a sip of tea.

Han Lin was startled. He suddenly raised his head, glanced at Wang Shen, and then lowered his head again.

"Actually, the murderer later came to a realization. She felt that if her boss and Han Mo were truly in love, then she decided to let them be together. So, she decided to go to Han Mo's house to talk to her. Coincidentally, and also because Han Mo was so careless, the door to her house was unlocked. Manager Han, guess what this woman saw when she got to Han Mo's house?"

Wang Shen's words seemed to have stirred up some memories for Han Lin. Han Lin clasped his hands together again, and the wrinkles between his brows deepened.

Wang Shen didn't expect Han Lin's answer and instead revealed the final result himself. "That woman discovered that Han Mo was actually entangled with another man. And the man who had the relationship with Han Mo had a scar on his back that was exactly the same as Manager Han's. Manager Han, don't you think that's a coincidence?"

After listening, Han Lin kept his head down and remained silent for a long time. Wang Shen didn't want to break the silence immediately; he wanted to give Han Lin more time to think it over and see what kind of feedback he could get.

After a few minutes, Han Lin finally raised his head and spoke. "That's right, I know Han Mo, and we do have a relationship. But our relationship isn't as complicated as you think. I only had sex with Han Mo once. I can swear on everything I own about that."

Wang Shen nodded slightly, observing Han Lin's manner of speaking. "Manager Han, what shoe size do you wear?"

"Huh?" Upon hearing Wang Shen's question, Han Lin looked at Wang Shen again with a puzzled expression.

Wang Shen didn't explain, but pulled a large sheet of white paper from his pocket. He unfolded the paper and examined it closely; on it was the outline of a foot. That night, when Wang Shen went to Han Mo's house to investigate, he encountered the garbage collector downstairs. Wang Shen bought a bag of trash thrown out of Han Mo's house from the old man at a high price. Inside was a pair of shoes. Wang Shen had drawn the shoe's outline on the white paper, and today he had conveniently brought the paper with him.

"Manager Han, if you don't mind, may I borrow one of your shoes?" Wang Shen asked Han Lin with a smile.

Han Lin's face was a mixture of complex emotions, but he still nodded. "The shoe cabinet is near the entrance," Han Lin said, pointing to the front door.

Wang Shen nodded, got up, walked to the shoe cabinet, opened it, and took out a right-foot leather shoe. He placed the shoe on a piece of white paper and compared it to a pre-drawn outline. Upon seeing the result, Wang Shen frowned slightly. Han Lin's shoe size was larger than the size on the paper; they didn't match at all.

Based on Wang Shen's investigation records and the information he obtained from the garbage collector that night, the shoe size on the paper should belong to a man who frequently visits Han Mo's house. However, judging from the current situation, Han Lin is unlikely to be that man.

Wang Shen put the shoes back in the shoe cabinet, carefully put away the piece of paper with the shoe size outline, and then sat back down on the sofa.

"Manager Han, could you tell me how your relationship with Han Mo progressed to that point?" Wang Shen's words were somewhat veiled, but Han Lin fully understood what Wang Shen meant.

"Actually, I only delivered food to Han Mo twice. The first time was that time, and the second time was the night Han Mo had the accident. Apart from that, I had almost no contact with her," Han Lin said with a sigh.
