You know what with how fucked up this author is. I know Shinobu will contemplate that suggestion instead of rejecting that idea outright. If i were in his shoes i would straight up reject that idea because why would i let my girlfriend take a nude photoshoot which is the most logical thing to do here. After all gravure idols doesn't necessarily need to do any nude stuff to sell their stuff.
What I'm worried about is Fumi, because we all know every single female characters in this fucked up manga are all gullible. I know Fumi will be in deep shit here, because the other director or maybe some other dude or a new dude will probably use Shinobu as a pretext to try to convince Fumi to undress or do a nude photoshoot like what the other guy did to her who almost succeed with his attempt to fuck Fumi if not weren't for Shinobu's intervention.
I feel like the same pattern that happened to Sakura where Shinobu will keep protecting her and be the first one to take her virginity only to end up being taken by another guy at the end is slowly happening to Fumi as well. It's like the calm before the storm type shit.
Anyways this feels like I'm reading a toned down version of Guilty Circle.
