Unpopular opinion, I guess, since I hear people complain about it all the time, but I love the miscommunication trope. I don't know why people claim it's unrealistic when I see everyone misunderstanding each other on a daily basis. Miscommunication doesn't mean not talking to each other (because I keep hearing "just talk to each other" when this trope is mentioned). It means the characters talk, but not clearly enough and you know what? That is real. People misunderstand me all the time and I am no stranger to misunderstanding other people.
