Transmigrated As the Fake Heiress

Min Yu glanced at the dark expression on Huo Yao's face. It seemed like she suddenly changed into a completely different person.

He tried to console her. "Your grandmother will be fine."

Huo Yao replied with a small nod. Her long eyelashes cast a shadow over her eyes as she lowered them. She was calm and not anxious.

Very quickly, the hospital ward door opened.

Huo Yao looked up and entered the place quietly.

The doctor removed his mask and looked at Huo Yao and Min Yu sternly. He reprimanded them in a severe voice. "She's okay for now but can't you youngsters watch your temper when she's around? Her heart is weak, and she can't afford to get agitated again and again."

Huo Yao's eyes glinted for a second but she replied with both humility and modesty. "I understand. We will be more careful."

She Can't Be Agitated Anymore
