Before meeting Cheng Yu, Nian Yuxi's world was very small, with only Sang Qi; after meeting Cheng Yu, Nian Yuxi's world was still very small, but Cheng Yu and Xi Sheng were added to it. At that time, she had no one. She was a cool and sassy female top student who attracted all the attention and could not be matched by anyone. Later, she was spoiled by three boys and turned into an unscrupulous child. She was still a female top student, but she became kind, gentle, lively and cute. At that time, she thought everything in the world was beautiful. When she was unhappy at night, Sang Qi would chat with her. When she was bullied while playing games, Cheng Yu would stand up for her. When someone made her cry, Xi Sheng would help her solve it... When did it start? She relied on them and she felt they would never leave. Later, the Sang family fell into decline and Sang Qi disappeared; Cheng Yu didn't reply to his messages for a long time and there was no news; Xi Sheng contacted her intermittently, but he refused to continue talking to her. She grew up almost instantly, from a "kid" who was pampered by three boys, to Sister Xi who was praised by everyone among the alumni of No. 4 Middle School, to an aloof and aloof schoolmaster, to a big sister who said "It's okay, I'll protect you" to her bullied juniors. People always change. She doesn't know where to find them, and it seems she can't go back...
Intention: The future is long, we must learn to be strong while taking our time. We will eventually grow up alone.
