Jin Shuang mustered twelve years' worth of courage to call Yu Zijian on the eve of Valentine's Day, her voice trembling as she forced out each word: "Are you free tomorrow?" Yu Zijian, hearing Jin Shuang's murderous tone, coldly shook her head. "No, I need to accompany my partner." Defeated, Jin Shuang threw her phone onto the bed and slept in a daze. The next morning, the doorbell rang. She got up to answer it and found Yu Zijian standing outside. Jin Shuang pressed her lips together and asked, "What do you want?" Yu Zijian raised an eyebrow. "To accompany my partner." When Jin Shuang was young, she wanted to give Yu Zijian the entire world. When she grew up, she wanted to be her entire world.
