Mr. Ye.
Nathaniel was a little stunned when he saw Ned and Carmel.
Why are you guys here? Aren't you still in isolation?
"Nathaniel was surprised when they appeared in front of him. He knew they were in quarantine and wondered whether they came in through normal procedures. Seeing this, he couldn't help frowning slightly."
"Ned looked at Carmel, who was obviously a little guilty. He held her hand and said, ""Mr. Ye, the virus has mutated."""
How do you know?
"As soon as Nathaniel finished asking, he noticed something."
Are you also...
"No, but I found something."
"Carmel had been dispirited these days, and she was used to everything that Ned had arranged for her. However, she realised that she should not act this way in front of Nathaniel. Then, she took a step forward."
What is it?
