Talk about fumbling around, Fumita went on a hiatus for months only to bring back a really short arc that basically ended the series at the first flag.
Bye Misuzu & friends, bye learning to romance, bye first sex, we get a boyish kiss and Fin.
I imagine the hiatus was because he either got too many ideas to make it last and wanted to take his time organising it all, but realised the series could go on for years yet, either he was just too busy and decided to go for the quickest logical ending he could go for. Tiny arc to justify them getting together, and we're set.
Disappointing, but then again we got 950 chapters of fun, so I just want to say thank you and I'll definitely miss this series.
