The language is witty and humorous. The characters have diverse and mysterious faces. The seemingly casual conversations are actually full of hidden meanings. The protagonist, who appears to be good-for-nothing and honest on the surface, is actually a big shot. The clever contrast between the characters makes people full of anticipation. After dropping out of university, he went to work for a security company. However, due to a dismemberment case that occurred in a local university, his father gave him a strict order to accompany his sister to attend university together. In order to, er, well, to better protect this city. (He actually wanted to have a good time on campus at first, but he wouldn't admit it.) Chen Jiahua, with tears streaming down his face and feeling extremely aggrieved, decided to let the brothers in the company endure hardships for a while. He would take all the blame upon himself and go back to the university campus which he had been away from for a long time. Facing the phenomena of cultural self-destruction in the university that was invaded by Western culture, such as the teachers being obsequious to foreign things and always referring to the West at every turn. Facing the unreasonable and unequal chaos in the university and even the dangers that this city was facing. Chen Jiahua decided to wait for the right moment to take action in the undercurrents. Together with like-minded brothers, he would be a noble, pure, and upright person. Of course, as a male university student who only knew how to convince others with reason in a rather timid way, Chen Jiahua was also quite good at using his fists and feet to have some "close exchanges" with international friends. After all, not allowing those Japanese and South Koreans to be arrogant was his principle. Of course, while fulfilling the main task of protecting his sister, it was quite reasonable for him to build good relationships with those beautiful girls, right? Chen Jiahua also turned around to look. Wow! This girl was really good-looking, but he didn't seem to have any impression of her. Seeing her approaching step by step, Chen Jiahua frantically searched through his memory and finally remembered the name of the person in front of him. "Oh dear, Teacher Li, what a coincidence! I didn't even have time to thank you for helping me last time. I really didn't expect to meet you again on campus." Li Ting gritted her teeth secretly and cursed in her heart, "I was in the same major and class as you back then!" But on her face, she showed an expression as if it was really a coincidence and said, "Yes, it's quite a coincidence. I wasn't even sure if it was you just now. However, since you're so grateful, you might as well find an opportunity to return the favor?" The language is witty and humorous. The characters have diverse and mysterious faces.
