I recommend 'Master's Cold-Blooded Wife' to you. The protagonist of this modern romance novel was a young lady who had lost her loved ones. In order to protect herself, she also hurt others. She was a cold, aloof, heartless, and rich businessman who had made billions of dollars. She vowed to pay back the pain that she had suffered ten times, a hundred times, and a thousand times. And the grandmother in the story was her spiritual pillar. I hope you like this fairy's recommendation. Muah ~😗
