"Girls don't have a home when they grow up." I didn't know what I meant when I first heard it, but when I looked back, I realized that I was from the end of the world. Xu Yian, who was leaning against the train window and watching every frame flashing outside the window, but his eyes were empty. At this moment, he was like a duckweed floating in an endless void, with no sense of belonging and no expectation of anyone coming. When the train arrived at the station, the entire city, which had just started to light up, was completely shrouded in darkness. Standing on the platform, Xu Yian looked at the people rushing to the next station and joined them. She knew that she had to go back to school at this moment. But when she sat in the car and watched every lively scene flashing outside the car window, the loneliness in her heart was strong enough to swallow her up, so Xu Yian closed her eyes and determined to light her own lamp among thousands of lights with her own hands.
