Similar plot lines and character dynamics. You have a uke who's in love with a man that abuses him (both emotionally and physically). Then you have the seme who's secretly in love with the uke but is afraid to make a move bc the uke is in a relationship. Even so, he helps the uke feel comfortable with him and waits patiently for him to break up with his abusive ex.
