At first, Ren had been furious about the betrothal. A normal human, chosen to be his betrothed? It was something that he found rather ridiculous. After all, how could you ever be expected to keep up with him, and furthermore continue the Tao bloodline if you weren't as strong a Shaman as he was?

Then you came to live with him.

He observed from a distance. Treated you with coldness the few times he interacted with you. He had been prepared to continue shunning you until you did the unthinkable.

You stood up to his father for him. You got in between him and his father without hesitation and without shamanic powers to protect yourself.

It was around then that Ren changed how he treated you. You showed true loyalty to him and it did not go unnoticed or unappreciated.
