Alright, I have a gameplay question now.
Why does Kotori sometimes (Actually, most of the time) lowers your image level after a sucessful audition if you have high stats? Is it something I did? Remember, I don't read Japanese except a few kana, so whenever Kotori comes after I win an audition due to an image level and stats I gained due to luck, I start shivering because I know she'll probably lower them.
Why does this happen? It's probably not Kotori herself going "MWAHAHAHA I'M GOING TO LOWER YOUR IMAGE LEVEL AND THERE'S NOTHING YOU CAN DO ABOUT IT!

", but well you know, I associate Kotori with such a horrible thing. I think it's probably just there to make the game more challenging, (after all, the game would probably be way too easy if you were at idol god the entire game) but I want to know that if that's not the case, is it because of some action I did in the past that triggers it?
