It was past nine at night when Rong Zhi and Bai Su, who were supposed to return to the villa earlier, finally arrived.
Pei Su was assembling a mechanical wristband. Lately, she had been learning mechanical knowledge with Rong Zhi and Zhao Hecheng, so she found two abandoned ones to study.
Though unsure why her sister arrived late, she glanced up at the red marks on her sister's neck, understood, and continued focusing on her own tasks.
But when she caught sight of the man beside her sister with her peripheral vision, her gaze paused.
Bai Su was always cold like the icy river, except when with Rong Zhi. Apart from the wristband given by Rong Zhi, he had no other accessories, and suddenly seeing a splash of red on his ear surprised her.
Jiang Gujun felt the same way when he saw the exceptionally delicate blood-red gemstone earring on Bai Su's earlobe. He quickly averted his gaze before Bai Su noticed, continuing to talk to Rong Zhi as if nothing had happened.
