They don't trust me

Noah returned to the rose castle after not getting any favorable response from his father and mother. He didn't want to argue anymore with them regarding the same matter because they did not understand him. 

His mother went on about the queen's duties and responsibilities but she didn't understand the main point that he was talking about. His baby dove attracted all kinds of dangers wherever she went. Worst of all, he heard about a rootless beastman entering the rose castle. Thankfully she was unharmed that day because that beastman left without doing anything to her. Even then, her shoulder was injured and Killian healed it on time.

This was the situation that happened even when she remained inside the house, so he didn't dare imagine what could occur if she goes out. That rootless beastman might once again approach her and worst those stray beasts could see her. His mate was too beautiful for her good.
