The student union from other departments came to the journalism class to recruit volunteers, and Xiao Tu was accidentally chosen. It was during this event that she realized the guy who had given her his phone number was actually a part of the student union. To spend more time with Xiao Tu, Ling Chao insisted on dragging her to attend early classes together. Xiao Tu was surprised to find out that Jiang Hu, the guy from the student union, was also from the computer science department. The two of them had a friendly and warm conversation. Ling Chao felt a pang of jealousy due to their friendly interaction. His roommates reminded him that if he didn't take the initiative, someone else might snatch Xiao Tu away. This woke him up, and he decided to use the collective wisdom of the dormitory to win Xiao Tu's heart. On Xiao Tu's birthday, Ling Chao wrote a code that arranged the lights in the dormitory building to spell out "Happy Birthday." He presented her with a gift in front of their classmates. This gesture stirred unique emotions within Xiao Tu, although they were somewhat unclear. She turned to the internet for help and received surprising advice: She was developing feelings for her childhood friend. (Source: Chinese = Baidu || Translation = MyDramaList)
