A follow-up to the HaruMatsu chapter from 6 years ago? Payoff for Harumin's character arc that's been teased for years? Hopefully we can get more of this, with Harumin (and Matsuri) taking the spotlight and Yuzu and Mei being in a supporting role. Or I wonder if Sabu will use Yuzu's letter to try and replicate the timeskip that happens during chapter 36 and use it to timeskip towards the last month of Aihara Academy...?
