I thought I had fixed this one 0_0 (maybe I forgot to re-upload it...)
Will reupload later on this week (currently doing Tocchan's route so it can't even be played right now)
I redownloaded the game and it worked. I did not get a cg for this one though (the first time doing it cg).
Hikaru's sex CGs are obtained if you manage to become lovers with him during matsuri festival.
