The Clue Frenemies, perhaps
The Answer USERS
The word "users" fits the clue "frenemies" because it describes people who may pretend to be friends but are actually using each other for personal gain. In many relationships, one person might benefit more than the other, leading to tension and conflict. This dynamic can create a love-hate situation, similar to what frenemies experience. Thus, "users" captures the essence of that complicated relationship.
