Until we see Sakura is really happy where she is or that fumi takes sakura's place in Shinobu's heart and mind it's not over and things could change I don't think they will but they can.If Fumi is accpeted, pretty safe to say manga is ending in a few more chapters and we won't have to worry about any more baits with Fumi. They'll become a happy couplle, finish the movie and step into the golden years of their career in the entertainment industry and maybe we get some awkward epilogue to try and guilt trip fuckboiXSakura if that is the case.
