The photoshoots happen successfully.
Sakura sees them.
Finds out the director was Shinobu.
She goes to demand him a talk about that moment.
He tells the truth, but also that he's now living and managing Fumi.
She mentally beats herself for jumping to conclusions, but sees in Shinobu's eyes that it's too late to start over, so she tells him she's gonna debut in a porn movie.
Shinobu supports her decision. She gets disappointed, as she was expecting him to stop her, but thanks him for his words. They part ways. But at least, she spares Shinobu from further scandals by framing him as the bad guy.
Final chapter is an after timeskip class meeting where ShiFumi+friends are drunl and one lf them sees Sakura's JAV when he tries to make Shinobu see it, he tells him to not show it to him, as they now belong to different worlds.
