Wang Yu asked Maria not to follow Orris anymore. On the one hand, he didn't want Maria to find out about the attack on Oris' Manor, and on the other hand, he was genuinely concerned for her safety.
From the events outside Oris' Manor that night, he could see that Maria was completely clueless about surveillance and tracking. If this continued, it was inevitable that she would be exposed, and once she was, death would be waiting for her.
She was Chang Fansha's girlfriend, and Chang Fansha was Wang Yu's brother. Naturally, Wang Yu wouldn't want his brother's girlfriend to encounter any mishaps.
Hearing Wang Yu's words, Maria slightly raised her eyebrows, then shrugged her shoulders and said, "I'm sorry! I didn't know my actions might cause trouble for you all. I just wanted to help Fansha. But I can promise you, I will never follow Orris again."
Wang Yu nodded, smiling as he said, "Maria, it's great that you can promise that. We all appreciate it."
