Zhiyuan's eyes shone as if the brightest star just landed on the earth. He grabbed her shoulder and shook her. "Really? You really forgive me?"

Xinyi felt her eyes roll in dizziness as Zhiyuan eagerly kept shaking her. She snapped out and coughed. "Yes…"

She was indeed furious at him for sneakily reading her diary, but she had also understood that Zhiyuan was genuinely apologetic. She realized that she was also at fault for hiding this from Zhiyuan instead of properly communicating with him.

A marriage needed communication as much as it needed love and trust between two partners. She was too stubborn not to let him know anything.

Plus, now she wasn't doing anything different. Han Huizhong would be just as furious to know that they entered the storeroom without their permission. 

Han Zongying for him was similar to how Xinyi's diary was for her.
