Save the redhead girl and don't take Hitomi to the clinic. Anti curse potion is only 3. Sleep in morning to slow the curse stack.
bro, the curse mechanic sucks. It is annoying as hell. Please make a way to permanently get rid of it in a future update. At the very least make it craftable or buyable once you finish the event in to get the anti curse potion. Logically if it was contagious in the game, then the whole thing would have been turned into a plague situation. So yea you made a good game except for the fucking curse mechanic.
I apologize for the unpleasant experience you had. It's true that the curse progresses quickly and is annoying. I've released another update, and while there's still no way to completely remove the curse, it will progress much more slowly. I will adjust the curse in the next update. Thank you for your feedback.
