The game is really good and really easy to unlock the scenes. There is no parameters or item you should care about, just go to the location you're told to on not really specific time (just weekdays and weekend), the story will goes and you unlock more scene with more character.
But I more interested in the main story now. I just want to know what happens next.
I don't even care if you didn't add any new h-scenes anymore if it means more main story. It's just that interesting.
Thanks for your hard work. I hope you can make it until the end.
