But why was it so short??!! (╯°Д °)╯╧╧ Things were finally happening ╥﹏╥...

it was supposed to be part of last month's chapter but she wasn't able to finish all of the pages in time because she caught a cold.

Will there be an epilogue chapter for this volume? Or is that it for the volume?

There's another chapter coming out next month. I don't know if that's the last one or not but I'm assuming it is.
