Is there a volumen 3 or is this the final volumen?

as of rn doesn't seems like there won't be a 3rd volume since this is marked as completed on Renta JP, I'll also add that the Official English did not translate the bonus chapters for Volume 1 or 2.

the author also said they didn't plan for more then 2 volumes, so it's completed

Damn, thanks tho (●'◡'●)ﾉ
