I dislike kids.
The main pair and the supporting cast was very fun and a sol series lives on its characters the swap mechanic was always just a cute gimmick.
Maybe people got bored cuz it tried to focus on relationships that never really went anywhere ? Introducing a lot of characters ? (personally i like them all especially the teach, what happened to the blackmailing couple though?).
More focus on the main 4 might have been good and developing them more before introducing others only thing we know about Yume is that she likes to eat and is always getting her request for a kiss refused and Satsuki is a good straight man, very responsible big sis type.
Go somewhere with the main couple at least like in Futaribeya if you dont want to straight up say it.
Welp anyways it is sad that it was so short, feels like it still had way more juice.
