I just finished this game and oh my god it is really amazing. I loved just about every route but I will say Fraser's, Osamu's, Aito's were the ones that stood out the most.
I want to say a lot but I will say I really really hope the possibility of epilogue game ends up happening because I really want to see more of how their relationship in each route after the good ends happens. Especially for Osamu and Fraser.
Edit: still thinking about this game and I really feel so bad for Osamu in his route. I really hope we an know more about what happens to him after his good end.
Again thank you for such a fantastic game!
