When I was preparing for the postgraduate entrance examination in the library, I chose a position near the corner. I thought there would be no one to disturb me without heating and windows in such an off-center position.

But! On a windy afternoon, I was sitting in the library studying Fourier and Laplace. A couple came over and sat opposite me. At first, they were normal. The man took a fake look at the data structure. The woman didn't read a book, just quietly playing with her mobile phone. But then, the woman suddenly leaned on the man's shoulder, and the man raised his right hand and began to touch the girl's face. A book with such a thick data structure fell on the table, and the spine of the book slammed on the table and scared me. I looked up at them and said nothing. When they feel that I am watching them, they may feel embarrassed and then return to normal.

But! Five minutes later, the two of them began to feel bored again. The man touched the woman's face and the woman leaned against the man's shoulder. They chatted and began to look at their mobile phones. One big bed room, the other special room. As soon as I heard it, it's time to start preparing for the evening! It would be much more interesting to say this than Fourier Laplace. I began to eavesdrop on the conversation (yes, I am so incompetent). From the room to dinner, and finally to tomorrow morning, I can hear clearly. I just need to give them some advice.

Later, the man may be thirsty and go downstairs to buy water. The woman was playing with her mobile phone in her seat and began to reply to WeChat (the mobile phone input vibrated and buzzed). Maybe she told her best friend about the boy? Later, the man came back, silently stood behind the woman and watched her chat with others, then put the water he bought on the table (damn, everyone in the study room looked this way), and the man left without looking back. Before the things were packed, the woman quickly got up and chased the man. I see what this is!

Take out lighters and cigarettes, pretend to smoke outside and see what's going on. When I came out, the two of them had already gone down to the first floor. The woman kept saying that he was a good friend (I think it was a man, because the woman said that she had no friends in engineering, that is, she had a good relationship with Li xx, a famous central air conditioner in the Institute of Technology). The man broke the woman's hand and left without looking back.

Just half an hour witnessed a bitter drama?
