It's because we need the closure. It doesn't sit right with us for the two to seperate and just forget each other when the whole 126 chapters was about these two. It's not something you can just throw away no matter how much you want her to.
Sakura, while yes enjoying a lot of sex, isn't so one note. She has a high sex drive yes but there's more to her than just that. We want to see what she thinks of it all. See what direction they're taking her. There IS a chance for her to mature. It doesn't excuse what she's done but there's a chance for character growth.
Are we expecting too much? Most likely. But it doesn't sit right for me and others to just toss Sakura aside. Don't get me wrong I'm not a fan of her either because of what she did. But we NEED this closure for Shinobu and hopefully he'll get it.
Sakura may even be set aside for a bit but she WILL come back into the picture. That's out of the question.
Yea this is it, obviously I don't want Sakura to go back to Shinobu, I just want the closure for Shinobu's case, I want Sakura to clearly know that Shinobu didn't cheat on her, I want the misunderstanding to be cleared up.
What happens after that? The best outcome is Shinobu moving on with Fumi but I really would not put it past the author to pull some BS and have Shinobu take Sakura back, people can deny this outcome, I want to as well but until we see Sakura's POV until she shows zero regret or breaks down in tears still thinking of Shinobu, anything can happen.
Regardless of what people here may want or not want, Sakura is probably going to meet with Shinobu again eventually, she's still the "main girl" as far as the series is concerned, even if Fumi takes the spotlight for a bit.
The absolute worst outcome I'm expecting is that Shinobu and Fumi date for a bit, have sex but Shinobu can't forget about Sakura, then we see playboy and blondie treating Sakura like shit or something, Fumi somehow reaches out to Sakura, tells her the truth, Fumi gets sacrificed and Shinobu takes Sakura back.
The best outcome would be that Sakura goes on a downward sprial, blondie starts to realise that Sakura isn't all that as time goes on and playboy either gets bored of her or doesn't protect her from being assaulted by directors or other actors, then Sakura gets hit with the bullet train truth of Shinobu not cheating on her, she tries seeking Shinobu out, they talk, but Shinobu makes it clear he's with Fumi now and wishes Sakura the best.
Sakura then resumes going on a downward sprial after Shinobu rejects her and either stops acting or decides to just go into the adult acting industry to drown in sex so she can't think about how badly she messed things up.
