"There's no doubt he wants to win you over, but since you're from the Wild Dragon Clan, he can't be sure if there's anything wrong with you. He let you absorb the Dragon Power, and this is definitely a way to draw you in. But even for the Dragon Clan, Dragon Power must be the most precious resource. Think about it, who would do such a thing shortly after meeting someone? He dares to do this, one reason being to win you over, to make you trust him more, so that after receiving benefits, you'll be loyal to him. Another reason must be that he has something to rely on. I don't think his own strength is sufficient for that, because if in the future you manage to become a Dragon Knight as he predicted, he won't be able to suppress you. So, the problem likely lies within your own body. After all, you've consumed his food, absorbed the energy he provided, and in this process, it wouldn't be hard for him to meddle."
