I have no clue. You seem to have an idea and maybe your idea pans out since you're usually right. The manga doesn't need to rage bait or ntr bait readers anymore, it needs to resolve THE remaining conflict to end things on a high note to salvage whatever they can for the volume sales.
It doesn't matter how much the truth matters to the characters atp, its about how it matters to the readers and how we've had to stomach for an entire month (and some extra), the fact that Shinobu got cheated on over something he never did and even now Sakura still hasn't learned the truth while supposedly (I don't think they have but I'll be fair and take the popular opinion) going out with fucboi until now. Sakura needs redemption, it starts with the truth, and I refuse to believe KA ego keeps ego'ing with Kodansha potentially bearing down and having already axed this, but 135 could change all that.
