I really hope that we get a sequel, though I kind of doubt it. At the minimum, I want the author to make some extras showing the girls meeting with boys. Maybe have Ajisai meet a boy who struggles as much as she does to be taken seriously. Have the Tigers meets some kids that can match them in their mischief. Show Hinagiku break down when she discovers how little impact her "cuteness" has on the boys. There are so many stories that can be made, long ones as well as tiny shorts, about the new meetings.
And if there is a sequel, I kind of hope that Sasanqua will find a boy who can relate to her, maybe one who looks up to Tsubaki's boy just as much as Sasanqua does, leading to the two teaming up. Don't even need to lay hard on the ship-teasing there.
