It’s short for polyamory. It’s basically someone having multiple relationships at once. Normally they’re all romantically involved. Someone may play the center, where one person holds the rest together, or they may all share equal feelings for each other. In Him & Him & Him it is one woman that receives the love of three men. A set of twin nephews and their uncle. They consider themselves exclusive. If you enjoy smut reading and are curious about such relationships it is not a bad read. But when it comes to poly stories you have to remember it’s never going to be just one single person, no one on one relationships. A lot of people have trouble reading/ understanding because of that.

white hair dude is the ML in the novel and the one she ends up together in the end, the other FL brother and her "dated" in the novel too and blue hair also liked her in the novel. but yes sometimes the webtoon isn't a copy cat of the novel so who knows if they switch who's going to be the ML, but nothing is confirmed, I still think the white hair is going to be the ML but who knows, with the blue hair popularity the author might change the ML to please the audience. or might write an alternate ending. someone can correct me if im wrong :)!! so yes the ppl who like her are white hair, blue hair, the brother, and the blond I think but the one she ends up with in the novel is the white hair.
I like how in the comments everyone is spoiling saying the ML is either blue haired, white haired, or the brother lmao we’re all so confused
