"Professor Lou knows that I also come from the countryside, and compared to Xue Yuxiu, the family situation is slightly better. Because of similar experiences, and because I was attracted by the persistent and positive attitude towards life from Xue Yuxiu, even though we were not in the same class, I often found opportunities to get close to her.

In the first half of my sophomore year, after the National Day parade organized by the school, I mustered up the courage to express my heart to her. At that time, although Xue Yuxiu did not explicitly nod in agreement, she did not refuse. And since then, it can be seen that she often inadvertently reveals her affection for me. ”

Jia Wei and Lou Jiqun did not interrupt Han Wensong's narration, and quietly listened to him continue: "Just when I was full of hope for the future of the two, because of Xue Yuxiu's excellent grades and positive performance, he was selected to go to Michian Reagan State University as a publicly-funded exchange student in the second half of his sophomore year.

I remember that the night before she left, we met to watch a movie, and when I sent her back to the girls' dormitory, Xue Yuxiu, who was standing at the top of the stairs, took the initiative to give me a hug. Even though she didn't say anything, I knew that she had accepted me in her heart. So much so that I didn't sleep well all night.

For the next three months of being separated from each other, we had to connect almost every day through the Internet to tell each other how much we missed each other. ”

"Is there only three months for exchange students?"

"No, it's half a year." Han Wensong's gaze crossed Jia Wei's shoulder on the other side and looked out the window and said, "Since the fourth month, the situation has suddenly changed. I didn't receive any more e-mails from Xue Yuxiu for a week. At that time, I thought she was sick, so I was very anxious. However, through other classmates who went to study abroad with him, I learned that Xue Yuxiu was not sick. I was in class every day, but I seemed to become very depressed overnight, and according to the classmate's description at the time, I was 'always preoccupied'. ”

"Why?"

Although I asked many times after that, I only received two emails from her in the remaining time. The content has also become extremely simple, just ordinary greetings, and never answered my questions. ”

"What about when you return home?"

By the time she returned home, the summer vacation had already passed. Because I was in a bad mood at the time, and I wanted to see her for the first time, so I could ask her face to face, so I chose to stay in school that summer and work part-time.

When they returned, I personally ran to the airport to pick her up. At a glance at Xue Yuxiu, I could hardly believe my eyes. ”

Han Wensong, who was caught in the memories of that year, became extremely depressed: "She has changed, she has changed too much." It is almost exactly the same as the photo of Du Xiaowei I saw just now.

Not only has she become beautiful and mature, she no longer looks like a student, but the clothes she wears are no longer the simple girl from a remote village.

Although there is still a hint of nostalgia for our beautiful past in her eyes, it is more of a strangeness, a wary look that rejects people thousands of miles away. ”

"Did she explain anything to you?"

"No, nothing." Han Wensong breathed a long sigh of relief and said, "Our beautiful first love ended without a problem." ”

"Later, I mean there are any other changes after Xue Yuxiu came back, or is there anything abnormal?"

"I didn't know where she had gone or if she had come home for a while before school started. After the start of her junior year, I heard from her roommate in the same dormitory that Xue Yuxiu rented a house off campus and moved out alone. Since then, Xue Yuxiu has become no longer gregarious, and she no longer actively participates in various cultural and sports activities in the school.

If Officer Jia takes a closer look at Xue Yuxiu's file, he will find that there are very few records of her participation in activities in the first semester of her junior year. ”

Jia Wei nodded and said, "Where did she get the money to buy clothes and rent a house?" ”

"Nobody knows."

It was definitely not given by the family, which Jia Wei, who had been in contact with Xue Yuxiu's mother and learned about Xue Yuxiu's family situation from his girlfriend Xue Xiaomei's seventh grandfather and other elders, was very sure.

That is to say, it must have happened within half a year of Xue Yuxiu's study abroad, to be precise, one day three months later.

But what happened?

"Didn't you ask your classmates who went to study abroad what happened to Xue Yuxiu during your study abroad?"

"I inquired, I asked almost everyone, but no one could explain clearly. It is said that Xue Yuxiu became like that almost overnight. ”

"Can Mr. Han still contact Xue Yuxiu's roommate back then?"

"I can still connect with someone." Saying that, Han Wensong took out a number from his mobile phone and wrote it down and handed it to Jia Wei: "Officer Jia, this female classmate's name is Qiao Xiao, and she is now working in a joint venture in this city. ”

"Thank you." Jia Wei wrote down the phone number and asked Han Wensong again: "Teacher Han, is there any other information about Xue Yuxiu?" ”

"Other?" Han Wensong thought for a while and said, "Listening to the students who went to study abroad, Xue Yuxiu later seemed to hate water. I don't even wash up with other classmates anymore, let alone take a shower together. ”

This made Jia Wei feel very strange, after all, Xue Yuxiu was born on the Loess Plateau, which was extremely short of water, how could he hate water?

"Why?"

"Again, no one can say clearly."

Since Han Wensong couldn't say it clearly, Jia Wei had no choice but to ask Lou Jiqun instead: "Professor Lou, have you asked Xue Yuxiu which subject has the best grades?" ”

"The teachers who taught Xue Yuxiu back then all said that she had good grades in every subject, and it was really hard to say which one was the best." Lou Jiqun turned his head to look at Han Wensong beside him and asked, "Wensong should know something, right?" ”

"It's true as Professor Lou said, but I do know a little."

"What?"

"In addition to the compulsory courses in the design of industrial electronics courses, Xue Yuxiu is very interested in philosophy, and has taken logic, which is closely related to philosophy."

"Have you obtained the relevant certificates?"

"Probably not. I asked her at the time, and she replied that she liked it, not to get any certificate. ”

"Does Mr. Han know the specific location of the house that Xue Yuxiu rented back then?"

"Yes." Speaking of this, Han Wensong's expression was slightly embarrassed: "To be honest, I haven't forgotten her in my heart until now." So, at the time I was trying to figure out what was going on. So when I heard that she had rented a house and moved out of school, I asked around, and I really got inquired. ”

After getting the address of Xue Yuxiu's rented house back then, Jia Wei asked Lou Jiqun and Han Wensong a few more words, and saw that the two had no other information to offer, so he got up and said goodbye: "Thank you for your cooperation, if you can think of anything in the future, please remember to call me." ”

Leaving his mobile phone number, Jia Wei left the school, wanting to go to the place where Xue Yuxiu had rented for a semester first. I hope to learn more information from the landlord about Xue Yuxiu, who behaved abnormally after returning from studying abroad.
