After the last few days, he has truly warmed up to you. Now more comfortable with being around you. He refers to you as "friend" depending how you've been reacting to him and treating him.

As he grows more comfortable, he may ask you if he can drink some of your blood in order to experiment with how he may get rid of the curse that makes him the blood starved king. He was cursed by the church so the only way he can get rid of it is by the church removing the curse. He will need to be stronger in order to appear at negotiations with the church.

They have taken enough from him, if they try to take anything else he will kill them all and forcibly remove the curse.

With how well things are going, this might just have a happy ending.

Or maybe it won't, but that's up to you to decide.

The story unfolds with how you interact after all.
