Victor Gideon's sweetness/gentleness/tenderness does NOT come from a pure & genuine love for his story's heroine (Grace) that is completely severed from ulterior motives that are attached or existing outside of himself. While we can INFER a broader range of emotions beyond angry outbursts, dripping annoyance, and moments of admiration toward Grace in his maskless facial expressions & body language, we AREN'T given explicit access to his personal inner thoughts & feelings (in cutscenes, not including rare glimpses in some scattered notes) the way we'd have an abundance of with characters in stage musicals. Victor's and Erik/Phantom's storytelling mediums utilize emotions very differently, with stage musicals prioritizing moody & exaggerated emotional expression via music, scores/songs/lyrics. It will be very interesting to portray Victor, who is way more impersonal, deceptive, and emotionally contained, through Phantom(s) that are more personal, genuine, and emotionally/mentally/physically expressive in a VASTLY WIDER range.
