Gee, I sure hope nothing bad happens to the Romeo actor that might prevent him from appearing on stage, thus forcing the protagonist to fill in at the last second, as he is the only one who has all the lines memorized from helping the female lead practice for her part as Juliet, leading to many doki doki moments as the two are forced to confess their love in a play, but perhaps there might be some truth hidden in those studied lines. Boy, that surely would be out of left field, so I can't imagine anything like this could ever possibly occur.
