Man, I'm still surprised to see Nagi show up, my biggest expectation for this chapter was fuckboy appearing in the present to give us a hint of his connection with Sakura but he hasn't appeared at all, blondie is also absent and instead NAGI appears.
We were all so sure that Fumi would reach out to Sakura or Shinobu would find a way to contact her but not a single person considered Nagi showing up, which really, REALLY puts Fumi winning Shinobu over into doubt.
To be clear, I don't think Shinobu and Sakura should get back together but if this Nagi and Sakura talk goes the way I think it will go, then that door hasn't just been re-opened, it's been blown open.
