"Since Grace is Helena's best friend, I thought I should call her that. Am I wrong? If so, then I wouldn't do that," Vernon cleared his throat trying to repair the mess he had just made.
It's been ten years and he had completely forgotten the timeline in his past life. He was used to addressing Grace as his sister-in-law for ten years. So, it became a habit and he casually addressed her the same.
Now that the topic had come in front of him, he slowly recalled what had happened in the last life.
After Helena's mother's death, somehow her father and Grace's mother became friends. After a while, they decided to marry each other.
Since Grace was Helena's best friend, she had known Grace's mother for a long time. So, she did not reject their union.
Instead she happily agreed to being Grace's sister.
