He gradually realized that his arrogant, willful, unreasonable, lazy, and selfish fiancée seemed to have changed. She had awakened the Star of Wisdom and paved traiblazed many inventions. Moreover, her cooking was superb and had completely captured his heart!

The new Tang Guo was bold, decisive, and valiant, but no longer cared about him anymore. That wouldn’t do!

Bai Ye took the initiative. “Tang Guo, have you forgotten that we’re engaged?”

Tang Guo retorted, “This doesn’t count. It’s just my father’s one-sided verbal agreement. It’s fine not to mention it!”

Bai Ye forced his arms around her waist and smiled proudly. “That won’t do. Little brats can’t be born without a father!”
