Interesting. So the famous director supposedly had no interest in Ekoda, or at least didn't actively showed interest. He probably picked up on who she really is, and thought not to indulge her.
It also seems like Shirosawa has the same vibe that director had in Ekoda's school days. He doesn't have even an inkling of lust for her; just 100% business. I'm sure this film with Ekoda will feel vapid, and he'll redo it with Honjou while being sexually excited.
