I stopped reading this at least 100 chapters ago. Last I remember he met her grandmother or something. Popped up on updates (as I am wayyyyyyy too lazy to just delete it) and I was like "Wait, the title of the chapter is The girlfriend and living together!?!? Holy crap, progress?!?! Meh I'll check in and see what's happening."
I can safely report, that no, no progress has been made. They are still doing the same awkward incel stunts, and still dancing around each other without actually facing each other. For no fucking reason, other than to drag this blood-drenched dead hooker of a manga through the mud some more. My time was wasted wisely spent reading other pointless manga! Cheers!
