The call was from Fu Sichen.
Ever since the cat-theft incident, Xiao Nian lamented about Pei Zhen using his mobile phone to send the text messages that got him into trouble. Despite that, he screen-grabbed their conversations; he hadn't been able to help himself.
In the distant future, when he would no longer be in the entertainment circle, he would be able to show and brag to others about how he "managed" his artist.
The daydream that he conjured up was beautiful. Only, when Fu Sichen's call came, the glamorous picture of a proud hero he created for himself immediately self-destructed.
Why was Best Actor Fu calling him?
Was he still sore about him stealing the cat?
He had already admitted it was all his fault.
There was no need for accountability on Pei Zhen's part at all. Xiao Nian was going to pick up the call with his trembling hand, but alas, mistakenly switched off his mobile phone instead.
Xiao Nian panicked.
