Xiu Mei didn't hug him back. She didn't understand what's happening, why did he suddenly hug her. Holding the box in one hand while the other hand hanging in the air, she was as stiff as a log, letting him hug her.
... but there was something different in his hug. He was not making her feel uncomfortable. Why? Why she is not disgusted by his touch? Why she cannot bring herself to push him away? Last time it was easily done, then why not again?
Xiu Mei: "Z-Zian….."
Zian realized something, reluctantly he pulls himself away from her. Looking at his shoes, rubbing his nose, sniffing once, he apologized. "Sorry, I got carried away."
He didn't dare to look into her eyes, afraid she will see through his soul.
