Before they separated, they agreed not to delete each other's contact information, and to let the other know if they ever changed it.
Every holiday, Xiang Yi would send a greeting. Sheng Yanzhi never dared reply. He was the one who had ended things, so he didn't dare reach for the affection the other person had offered him.

A few years ago, Sheng Yanzhi always walked ahead, with Xiang Yi following behind and tugging at his schoolbag strap. This time, Sheng Yanzhi was walking up the stairs when he suddenly stopped and asked:
"Do you still want to hold on?"
Xiang Yi didn't work especially hard while studying abroad. Being clever was an advantage too. He always let himself miss Sheng Yanzhi, and when he saw him again, he was still smiling just like he had back then.
