Spring, summer, autumn and winter (GL)

After a few seconds, she let out a short sigh.

Zhang Zinan was listening to music with headphones on in front of the small table on the upper bunk, shaking his head while doing the ppt for his literature homework.The door of the room shook slightly, she stopped to listen, but she didn't hear anything, she continued to work on her own.

After a while, she lifted the curtain of the bed and took a look, and saw the person sitting at the desk in a daze, "Tang Chi?"

"When did you come back?" She climbed out of the bed in surprise, feeling that she was in a strange state, "What's wrong?"

Tang Chi's face was pale under the light, his eye sockets were reddish, and his eyes were still.

"What's wrong?" Zhang Zinan approached her.

Tang Chi's eyeballs moved, as if she had just seen Zhang Zinan in front of her, "Oh..." Her consciousness just came back now, and when she came back, those movements and eyes also came back together.

Zhang Zinan saw that her reddish eye sockets tended to spread, her cheeks turned pink, her emotions looked complicated, she didn't seem unhappy or happy, but rather frightened.

"It's nothing..." Tang Chi replied in a low voice, got up to clean up the desk, and took out the things in her bag. Zhang Zinan looked at her, "Hey, what I said this morning... well, talking about Professor Shi behind his back is a bit wrong." Great..."

Tang Chi paused, "..."

"Well...we're not arguing, are we?"

Tang Chi was distracted: "Oh...it's okay." She murmured, avoiding Zhang Zinan's questioning, and went about her own business.

Zhang Zinan didn't think too much about it, but in the next few days she realized that something was wrong with Tang Chirp. In the past, her daily life was very regular, with classrooms, libraries, cafeterias, and dormitories. Her time of day was about the same. And the time of chatting with her is almost the same every day, but recently she is more silent than when we first met, not the kind of silence of thinking, but in a daze and entangled.

Zhang Zinan had no choice, because Tang Chi refused to communicate with her, so she could only wait for her.

It was another week of tutoring time, and Tang Chi stood under a golden old ginkgo tree in the teacher's dormitory area for a long time before slowly going upstairs.

The lovely Qiuqiu came out of the familiar place, and Shi Hai and Mi Xue stuck their heads out to greet her.

Shi Ci is not there.

"My sister is on a business trip. She seems to be in Shanghai for a meeting or something." Shi Hai said.

"Haha, it's just the three of us, there are no parents anymore hahaha! Freedom! Freedom! freedom!" Michelle laughed.

Tang Chi walked in slowly, and for a moment, a kind of emotion flooded through his mind, he didn't know whether it was nervous or relaxed.

During the break, Tang Chi took his mobile phone and searched —— Journal of Operations Research Society of China, Journal of Operations Research, Shencheng University Shencheng Operations Research Society Member Conference held at Shencheng University...

Shi Ci is really on a business trip.

"What are you looking for?" Mi Xue leaned over to look at her screen, and Tang Chi subconsciously buckled down the phone.

Mi Xue had already seen a few words, she bent her eyes, "Are you thinking of Sister Shi?"

"...I just searched out of curiosity." Tang chirped softly, and suddenly thought of something, she asked Mi Xue, "Did you always call me sister Professor Shi?"

Michelle tilted her head and thought about it, "Yes."

"... She asked you to call... and..." Tang Chi's eyes fell to the phone screen, and her face was reflected on the dark locked screen.

"emmmm..." Mi Xue was surprised, and explained word by word, "...Shi Ci is Shi Hai's sister, so I call her sister," her voice suddenly lowered, "but I think Given the age difference between me and her, I can actually call her Auntie..."

"What are you talking about?" Shi Hai asked when he heard them talking.

"Oh, I said I should call Sister Shi to be Aunt Shi." Michelle said in a normal voice.

"Hehe, if you don't want your little life, you can call her that." Shi Hai mocked her.

Mi Xue stuck out her tongue, "I dare not, oh!" She turned to Tang Chi and widened her eyes, "Did you notice that Sister Shi is not here, so I dare not talk about her loudly behind her back!"

"Hahaha, you are so cowardly..." Shi Hai laughed at her.

After finishing her tuition, Tang Chi came downstairs, and the feeling of autumn became stronger and stronger. It was dark before six o'clock. She stepped on the leaves, and the slightly cold wind blew on her face.The dialog box of Shici in the WeChat software on the mobile phone is quiet and there is no new information.

Sister or something... it's really complicated.

Next weekend, because of the autumn school sports meeting, the tutoring was suspended for a week.

Tang Chi went to the big playground of the university, found the headquarters of the Faculty of Arts, and came to the camp of Shi Hai's class.

Shi Hai was participating in the [-]-year long-distance race. Michelle was standing on the highest step beside the playground, holding a loudspeaker and shouting at him, "Come on! Come on! Shi Hai! If you win, I'll be your girlfriend!"

The first lap of the [-]-year long-distance race has just started, and Shi Ci ran in third place. When he heard this, he slipped and almost fell, but was immediately overtaken by a person behind him. He gave Michelle a vicious look and burst out thick.

"Hahaha, I love you." Michelle gestured to him with her fingers, and then raised her arms to her head, not angry at all.

Tang Chi was a little reluctant to stand next to her, it was too eye-catching, Michelle pulled her over, "Come on, let's cheer for Shi Hai together!"

In such a noisy environment in the big playground, Tang Chi looked around quietly.
