I think you could fall in love with anyone if you saw the parts of them no one else gets to see. Like if you followed them around invisibly for a day and saw them crying in their bed at night or singing in the shower or humming quietly to themselves as they make a sandwich or even just walking along the street. And even if they were really weird and had no friends at school, I think, after seeing them at their most vulnerable, you wouldn’t be able to help falling in love with them.
