"Tianxin!!" Shen Xin called out to her again, "What are you standing there for? Aren't you always affectionate with your brother Chen Yiran? Why are you acting shy now?"
Chen Yiran frowned slightly.
Ever since she and Lu Yixiao came in, Shen Xin had been stressing that Lu was just their cousin. Was she... planning to hide something?
Chen Yiran's deep gaze shifted to Jiang Bei and saw a look of confusion in his eyes.
Tianxin hesitated for a moment, but urged on by the persistent Shen Xin, she plucked up her courage, extended her small, delicate hand, and gently wrapped it around Chen Yiran's neck. Then, she leaned in and planted a kiss on his soft lips.
When she raised her head again, Tianxin's face was full of blush, radiating shyness.
Shen Xin smirked at Instructor Jiang and said confidently, "See, this is the affectionate kiss between a cousin brother and sister."
Chen Yiran frowned, watching Shen Xin thoughtfully.
