Cruel?
Chen Yan found it somewhat amusing. How cruel did she seem to be?
Gu Jingcheng kept silent, worrying about how it might affect her when Su Tong said those things in front of her. Gu Jingcheng tacitly agreed with it, even until the end!
Gu Jingcheng initiated the breakup.
Well, since Gu Jingcheng proposed the breakup, would she have to keep pestering him if she didn't accept it?
No, that was not her style.
In all those years of emotional bond she shared with Gu Jingcheng, she did love him. But! She would not humiliate herself in the process.
There was no need for Su Tong to bother with these things in front of her.
Chen Yan gestured to the door and told Su Tong, "Leave. Here's not your territory. If you and Gu Jingcheng enjoy these performances so much, why not move to the entertainment world?"
