A Noble Lady's Chamber Life

I woke up in the body of Adeleide, the supportive female friend of the Female Lead in a novel my friend wrote. But the kind, shy Female Lead only seemed to care about herself, so I decided to stop going along with every one of her whims. She's an adult, she can't rely on me for every littke thing! And now the playboy second male lead, who is supposed to be cold, visits me all the time? Everyone's personalities seem so different, how is this story going to play out?! I just want to live a quiet homebody life!!
