Rachel didn't really have a longer fleshing out for her character huh... I hope dev's gonna do a solo ending for Rachel. Moreover, it needs to be really long and give us a satisfying ending with her. Uno too, needs a solo ending where the plot will involve her parents or something, a long one too!
Lastly, if possible... we get to have some more updates on this. Like more snippets of their harem life and some more romantic interactions. Everything doesn't need to be about sex, the cute and wholesome moments experienced along the journey may still be used to give us a small look on their future. Seriously, good shit.
Best wishes for their new game.
