even this is not full flashback, somehow i glad that ayano like isshiki and acknowledge his efforts. dude burnout and that jerk director just being mean as shit. its might be wrong but it what he needed after all that suffering. you need at least one person to tell you that you matter, and your efforts is not wasted at all. plus it not isshiki making move on her, he just wanted to be like father or big brother to ayano at his point of view. he knew what meant to be alone, and looking ayano focusing her career, he wanted to support that. while ayano, lacking of familiar love, view his attention on her differently. well, i not blame her, girls always have that kind of puppy love towards older man when they are young. but to act on that, i said that she is daring.
