You should still be perfectly fine with your current save file!
And don't worry about asking questions, that's what I'm here for!~
Thank you so much! Yet I feel still embarrassed from doing so. Also, to inform you, there is still a bug, again involving Tarius quest event, when I talk to any female that was involved in the event, it automatically takes you to Tarius' dialogue event. So it is not possible to buy or get anything from the girl desire that is in the Letter Association. Also, also... the bug concerning Lanch room... is still happening. I had to set his relationship points to 0 so it will stop.
