I know I've laid into this game. Cuz 1. I do enjoy the dynamic(Though I wish we didn't get a sperm cut off, lol) and 2. I still felt our MC was a fucking idiot.
But I feel and am glad to see he's starting to finally use the grey matter in his skull. Hands down, Nana is the MVP in this update. Amazing. I was also happy to see our MC and Father starting to mend those fences. I can't wait to see the fence mending we'll have with our Mam. Finally, FOR F's Sake, Deb & MC are working their shit out and are together(If you chose to go that way). I was nice to finally see us have that option.
Last but not least, I am glad we finally found that USB, I know this other part of the story(The Mystery of it all) sorta taken a back seat to everything(I'm 100% fine with that for now, I feel family stuff needs to aired out for a bit and taken care of). But I'm glad it's not being forgotten about.
Now we need a proper "Harem" setup. Yes everyone is well aware of each other, but I would love to see all them together and MC expressing to each of them in front of everyone else, going down the line explaining his love, affection, and adoration for each of them. So others can see that as well, maybe establish your Top Lass as for Harem "sisters" (When I mean Top Lass, sorta head of the Harem kinda thing(Either Deb or Milly or both together).
Overall, I feel this has improved greatly and still really into what the mystery of underlying story also. Good work sir, keep up the work.
