Not sure if you've read the rough TL yet, but I think one thing I'm almost sure of is Sakura will transfer to Mio's agency and even if she doesn't end up back together with Shinobu she'll be much happier with an agency that supports what she wants to do (Gravure), and will be around mostly good friends (Mio the Goat, Nagi is ok too). I have no idea in the remaining time left if we even see any further progress on the movie beyond a time skip honorable mention of how it went, we'll have to see. I'd much rather whoever is writing try to come up with a bs force MC's back together scenario atp.
