"What I mean is, I was just about to go downstairs to buy groceries," the old woman said, lifting the groceries in her basket halfway up and waving them in front of Wang Shen and the other two. "I ran into Xiaowen. She seemed really down, so I asked her what was wrong. She didn't say why, just that she had to go back to the clinic. And then she left."

"Grandma, do you mean she went back to the mental health clinic?" The young policeman seemed somewhat surprised.

“Yes, that’s right.” The old woman said, nodding exaggeratedly.

"Great!" The young policeman clapped his hands. "Then we can go to the psychiatric clinic to find her; her boss must be there too."

"Alright, you guys go ahead, I have to go back and cook dinner for my husband." With that, the old woman turned and headed towards her door. But halfway there, she stopped and turned back to stare at the young policeman. "By the way, young man, I think you and Xiaowen must get along very well. When you see her later, could you please talk to her and tell her not to be unhappy over a man who isn't worth it?" After saying this, the old woman happily went into her house.

"You're quite the liar, a natural-born liar," the older policeman said quietly, patting the younger officer on the back as the old woman entered the house. The younger officer scratched his head sheepishly.

"Alright, we need to get to the mental health clinic right away." Unlike the other two, Wang Shen wasn't relaxed; the slight frown on his face remained.

The car stopped again at that intersection known for its high crime rates. As soon as the engine was turned off, Wang Shen and his two companions jumped out and rushed into the building housing the mental health clinic. They ran all the way to the clinic's floor. The public areas were still brightly lit, but from a distance, the clinic itself appeared completely dark.

"Is anyone here?" The older policeman looked at the dark psychological clinic and asked Wang Shen.

"Let's go take a look and see." Wang Shen took a few steps forward and walked to the glass door of the psychological clinic. Wang Shen pushed the glass door with his hand, and the door was not locked.

"It's open!" the young policeman exclaimed in surprise.

"Everyone be careful," Wang Shen said, turning to the two people behind him. He took out his phone, turned on the flashlight, and the three of them slowly moved into the psychological clinic, following the dim light.

Although it was just an ordinary psychological clinic, the darkness after nightfall still sent chills down one's spine. The light from a cell phone flashlight could only illuminate an area of ​​about four or five meters ahead. With each step, Wang Shen would use the flashlight to check the 270-degree area in front of him before moving forward. The flashlight beam slowly moved from the left to directly in front of Wang Shen. The circular spot of light gradually fell on Xu Wen's desk. Suddenly, the circular spot of light trembled. Actually, it was Wang Shen's hand that shook. When the spot of light finally settled steadily on the office area, the three of them gasped.

"Xiao Liang, go find the power switch and turn the lights on," Wang Shen quickly instructed the young policeman without turning around.

"What are you doing here?" Wang Shen's eyes were fixed on Xu Wen, who was sitting in the chair. However, he could only see her back.

The person is still alive. Xu Wen heard Wang Shen's question but didn't answer. Instead, she moved her chair and slowly turned around. Xu Wen's makeup was exquisite, as if she had put on a meticulous makeover. She was even holding the couple's cup in her hand, examining it closely. After a while, Xu Wen gently kissed the rim of the cup with her red lips, a wicked smile appearing on her lips.

“Do you know what?” Xu Wen’s red lips left the rim of the cup. She turned her head slightly again to look at Wang Shen. “This set of cups is the only gift he’s ever accepted from me.” After saying that, Xu Wen laughed heartily again.

"But! He didn't cherish it!" Xu Wen's emotions suddenly shifted drastically. She stood up from her chair and slammed the cup in her hand to the ground. A loud crash followed, accompanied by shards of broken porcelain flying everywhere.

Wang Shen and the older policeman took two steps back, looking at Xu Wen with surprise. At that moment, the lights in the psychological clinic came on, and everything seemed to regain its brightness.

"Don't get agitated, let's talk this out." Wang Shen held up his right hand, palm facing Xu Wen, signaling her to calm down.

"Don't come any closer!" Xu Wen shouted, taking a glass container from the table with a skull-shaped label on it.

"Run!" Wang Shen suddenly shouted. The three of them immediately ran away.

Xu Wen swiftly pulled the stopper and poured the liquid from the glass bottle in front of her. Wang Shen and the other two saw the liquid hiss and emit white smoke the moment it touched the marble floor. After a while, the smoke dissipated in the air, leaving behind numerous craters on the ground.

“It’s a strong acid,” Wang Shen reminded the other two with a furrowed brow.

"What exactly do you want?" Wang Shen's gaze turned cold as he met Xu Wen's crazed eyes.

"I don't want to do anything, I just want you to hear my story." Xu Wen laughed a few times, clutching the bottle of strong acid that was still more than half full, and then sat back down in her chair.

Wang Shen placed his hands behind his back and waved to the two people behind him, signaling them not to make any rash moves. Wang Shen glanced at Xu Wen, pointed to a chair nearby, then pulled one out and sat down. Wang Shen's gesture reassured Xu Wen somewhat. The angry expression on Xu Wen's face softened slightly.

"I've known him for so many years, I can't even remember. Ten years, I guess." Xu Wen began to recount how she met Song Mu, her eyes filled with the beauty of memories. "Ten years, what does that mean for a woman? You men would never understand. Back then, I was a freshman, and he was a sophomore. I first saw him at a school debate competition. He was wearing a white shirt, which was very fashionable at the time. The moment I saw him, I liked him. No, I fell in love with him. From then on, I joined all the clubs he was involved in, and participated in all the activities he organized. I even went to listen to their psychology lectures whenever I had free time. I studied economics and management, and to be honest, I wasn't interested in those psychology terms at all. But you can understand, right? When you fall in love with someone, you want to see them every minute of every day." As Xu Wen spoke, her previously gloomy expression finally changed noticeably, and a slight smile appeared on her lips, a hint of girlish joy.

"But he was just too outstanding back then. Or maybe that's not quite right, he was always so outstanding. So, in college, I was just one of many admirers, completely inconspicuous. But I promise, I worked harder than anyone else."
