So this has to be a "poor translation" thing, but looking up to someone does not in any way correlate to feelings of the heart in english.
looking up to someone is purely an idealization of the mind, like you logically think of someone as a role model or a goal in a logical outcome.
Heart = romance for feelings in english, the heart and romance are the english version of Eros. Pragma is the "looking up to someone", and most people look up to a parent or authority during development
