With the insults that everyone was hurling at Jean, Wendy was so very pissed that she wanted to teach these people a lesson. But at the same time, she had to obey Jean.
She had experienced smirks and insults like this when she was in secondary school; they would find any means to frame her and then bully her. She managed to survive secondary school all because of her strong will.
Now, if she were the one being bullied, it would be fine, but it was her Young Madam—the very first person who showed her care and concern after her parents abandoned her without any hesitation. She didn't want anyone to dare criticize her Young Madam, and it seemed she had to train harder now.
