Gu Mengmeng wanted to turn him down. She felt that such a position was too suggestive.
Besides Lea and Elvis, she could not accept being hugged this way by others. Really, it felt extremely uncomfortable.
Gregory could tell her discomfort and did not force her. He only said calmly, "The temperature here is much lower than on ground. You will freeze if you do not cover yourself with beast skin. Elvis and Lea are not around. Even though I am just a guardian beast, I also have the duty to protect and take care of you. It's just feeding you some fruits, you don't have to be so repelled, I know my place."
In fact, Gu Mengmeng did not think that much as all her actions were reflexive. After Gregory said that, she felt a little embarrassed.
She tarnished his reputation and ruined his life. Originally, she wanted to treat him better, but she forgot that in the Beast World, it was not kindness to 'not cause trouble to others'.
