Qiao Yue was genuinely happy that her grandfather had returned to the country so soon.
As she had not stayed in S-country for long, she did not know what had caused him to fall into a coma. Before she left, Qiao Yue had asked Lu Ying to remind Qiao Xuan to pay attention to the people around the old man.
Seeing the old man hale and hearty, Qiao Yue deduced that Lu Ying did as she asked, passing on her message to Qiao Xuan.
Qiao Yue had returned to the Qiao family to fulfil her mother's last wish. After meeting her grandfather in S-country, she felt she could face her mother's request with greater sincerity.
She could tell that the old man loved her mother from the bottom of his heart; it was as if nothing her mother ever did could disappoint him. Now that the old man was back, taking care of his health was the highest of her priorities, followed by investigating the secrets surrounding her parents.
