Fokin hell man, best doujinshi I've read for a while now. Author's granted every sensei route fans' wishes. 10/10
And please ignore chapters #4 & #31. Many brothers have fallen to the author's snare. Heed my warning, and thou shalt avoid destruction upon thyself and thy future, and will be blessed for eternity.
I haven't read any of the source material, but I feel like this will have been more satisfying by the end. Specifically ch38. That was so wholesome I could hardly take it.
I've always felt this route would have suited the story more. Hachiman could continue to fight against normal life and normie expectations while finding happiness.
