QQ romance, the meeting, acquaintance, and eventual farewell between people.

Yuhua is a semi-illiterate in the Internet. Before coming to Guangzhou, she did not know what QQ was and thought it was just a trinket for children.

However, there are always many coincidences in life. The encounter, acquaintance and farewell between people are sometimes composed of many coincidences.

April is a rainy season. Ling Yuhua was attending a public math class when her mind was wandering outside the window into a dreamy haze. She was brought back by the flashing light of a text message on her cell phone. When she opened it, it turned out to be a message from her roommate: "Hua Hua, do you know any senior students? Can you borrow me the books Psychology and Pedagogy? I need them urgently tonight." Just as Yuhua was about to reply, her phone ran out of credit. She smiled and asked a classmate sitting next to her for help, asking him to reply to her roommate that everything would be taken care of and she could rest assured.

Afterwards, Ling Yuhua had only one thing in mind - how to borrow the books. One way was to go to the library, but the library might not have such books, otherwise her smart roommate would have borrowed them already; another way was to borrow from the senior students, but the phone was inconvenient, and besides, her phone only had one phone number of a senior student. So she decided to take the second approach. She still had to ask the classmate sitting next to her to send a text message to the only senior student's number. Unfortunately, this student was not at school. Although he promised to help, he could only borrow the book on Monday. Time was not on her side, and Yuhua was racking her brain again. Unknowingly, the bell rang for the end of class, and Yuhua grabbed her shoulder bag and rushed out of the classroom.
