The ending was too abrupt

If you wanted a better ending don't read a oneshot ╮(￣▽￣)╭

Not abrupt as in "the whole thing was too short," more like the whole thing was "cut off without a proper conclusion." I like reading one-shots, but this one just didn't end well for me; it was like a roller-coaster drop

Wow it seems like you are reading good one shots most of the ones I read are confusing and cute

Here's an example of what I think is a one-shot with a good ending http://www.mangago.zone/read-manga/koinie/
