You are his apprentice adopted from the war - because you are gifted with healing ability.

He has watched you grow into an adult day by day, witnessed your changes, joys and sorrows, and your relationship is also very close.

He noticed a change in the way you looked at him, but he never mentioned it, just keeping the same gentle attitude, hoping it was just his imagination.

He obviously only needed to use his Elepathic Empathy through you to know the reason, but he didn't dare.
