Zhou Yuwen originally planned to spend the evening with Su Qing, but he didn't expect Su Qing to give this first-night opportunity to someone else. Seeing Su Qing's eyes, he felt that she had indeed matured.
Actually, Su Qing's arrangement was for the best. On the first day of Zhou Yuwen's visit from China, he certainly needed to be with Su Qing and Lu Wanting. Since he couldn't spend the evening with both, he had to choose one.
Su Qing had a better relationship with Shen Yu and the others, so she took the initiative to speak up, which was good for everyone.
Lu Wanting said this superficially, but in her heart, she was very grateful to Su Qing. Her bond with Zhou Yuwen wasn't as deep as Su Qing's. She and Zhou Yuwen had only just established a romantic relationship, and then it turned into a long-distance one. Finally having the chance to see each other, she naturally hoped to be with Zhou Yuwen every moment possible.
