Chapter 150 has confirmed it, this mangaka is officially completely out of ideas but doesn't know how or want to end the manga. Like what the actual fuck happened to this manga lmao, it was never spectacular or anything but it used to actually be pretty good. Now its just been filler for the past ~30 chapters. Whatever, I'll still read it for the softcore shit.
I'd bet money this is getting axed sometime in the next few months though.
