Han Zongying didn't agree to go to the banquet because Han Huizhong had suggested it to her. She knew that An Guoting would be there too. She found out that the host had business relations with him, so it was natural that he would be present at the banquet too.
She didn't actually understand why she wanted to go. But only one feeling was going back and forth in her heart, and that was to see him again. The past month had made her even more desperate for him. She also wanted to see it for herself once again if he had truly moved on and if he genuinely thought nothing of her.
Han Zongying waited for him at the banquet. Then she saw him coming in. Her heart automatically skipped a beat. She nudged the host to introduce them.
As expected, An Guoting was a little shocked to see her, but it quickly resided. It wasn't impossible for her to be at such parties. She was Han Zongying, after all.
But it happened once again.
