SO as I see these are the possible outcomes:
1. She self-destructed her career just to make hime confused and go through an existencial crisis between being an otaku idol and is unholy obsession of putting her on a pedestal (highly unlikely)
2. Her manager goes ballistic over these false acusations and start too look at the source which very conveniently will point at him, she is going to pull the innocent card and It will be the stalker episode all over again just that this time will be worse (I'm betting this)
No matter what this guy is going to get royally screwed.
