The Hero's Love

Must... make be in... LOVE!

The person who the Hero has taken a romantic liking to but has no relationship with beyond possibly friend. The Love might not acknowledge the Hero's affection for them or might not think kindly of it and feels that it's an annoyance. The Hero may feel motivated to do whatever would make their Love happy, meaning they might even go as far as putting their own life down if it meant saving the one of the Love.
