Akira, as the protagonist, is probably the central figure in the play 'Whispers in the Attic' and will have interactions with all relevant characters, which includes both antagonists and supporting roles. Yuko, who plays the antagonist, will primarily interact with Akira, since the protagonist and antagonist are typically the key opposing characters. Yuko will also have significant interactions with Takeshi, since Takeshi's role requires heavy interaction with her character, the antagonist. This implies that although Takeshi's character may not be the central role, he is crucial to the development of the story, especially concerning the antagonist's narrative arc.

Hiroshi, the director, is not acting in the play but holds the overarching responsibility for the entire production. He directs the portrayal of all characters and orchestrates how the actors, including Akira, Yuko, and Takeshi, interact with each other on stage. Therefore, Hiroshi has a professional relationship with all three actors, guiding their performance to bring the play to life. His relationship with the play itself is that of a visionary and executor, realizing the written script through the performances of the actors.
In a theatre group, there are four members involved in the upcoming play titled 'Whispers in the Attic': Akira, Yuko, and Takeshi are the actors while Hiroshi is the director. Each actor plays a unique role in the play: Akira is the protagonist, and Yuko plays the antagonist. Takeshi's role requires him to interact heavily with the antagonist character. Explain the working relationships among the members of the theatre group, especially the interactions between the actors during the play, and outline Hiroshi's relationship with the play and the actors. Respond briefly.
