Song Sichen, a child from another family mentioned by his parents, was Lu Zhinan's crush. Lu Zhinan fell in love with him the first time she met him. He was "poison". Every time she saw him, she would play a little love song in her heart, imagining that one day he would become her prince. Unfortunately, her wish did not come true. A girl named Chen Wantang appeared next to Song Sichen. They were inseparable every day. She also studied very well. At school, everyone called them a match made in heaven. Lu Zhinan was depressed and wanted to see him every day, but as soon as he saw him, he started to fall in love again. She avoided him and made up her mind not to like him anymore, but one day when she was riding the bus home, Song Sichen sat behind her and she dropped her things. Song Sichen just picked them up for her and handed them to her. The inadvertent touch of his hand made her fall in love with this person again. She added his WeChat account in the name of club activities and kept an eye on his WeChat Moments. However, this person didn't seem to like posting on Moments. She watched him for several days and didn't post a single one. Finally, that day, he posted a message on Moments, but the mobile phone signal was too poor to load the picture, and it was still raining outside. She couldn't care less and ran home in the rain. She refreshed it again with joy, but when she saw it clearly, the smile on her face suddenly disappeared. He made it official... Sure enough, it was Chen Wantang. She stared at the phone for a long time. She tossed and turned and couldn't sleep at night. She looked at the moon in the sky and sighed in her heart. The distance between herself and Song Sichen was probably farther than the earth and the moon. Three years later, Song Sichen also had several girlfriends, but Lu Zhinan still paid attention to him. She still couldn't let him go and she still liked him very much. This was the case until graduation. On the day of graduation, Lu Zhinan mustered up the courage to come to Song Sichen but only said four words, "Happy graduation." Song Sichen smiled softly and said, "Happy graduation."
