Going by the reviews, I think I'll wait to download this in a year or two. Considering your work, it'll be much worth the wait.
Also, thank you so much for allowing a harem option in Once in a Lifetime. If ever there were a part 2, then it would probably evolve (or devolve, depending on how you look at it) into something like The Headmaster combined with Hero Harem Guild. Which actually might not be too bad.
