This work hinges on the surprise reveal that our cute JKs are both psychopaths, but it's so short and done in such a way that it doesn't really evoke much more than a "huh, ok" kind of response. The whole bullying situation was very flat and plot device-y which doesn't really work well in this genre without substantial stylistic changes, and on top of that I have a hard time seeing this narrative working as anything other than a oneshot (i.e. it'd be a very weak start is this were to be used as ch.1 for a series).
