The Best First-Person Perspective Experience

I seem to have traveled to many places and met many people. First person (it actually feels like a third perspective hahaha), describing other people's love or family relationships from the perspective of a passerby. I won't forcefully add my own emotional line (there are male and female, male and female, female). Will the title say he or be and the setting? Just choose what you like. (In my stories, most of the girls are good, and every character has a brain) Concept: Everyone is unique
