A Noble Lady's Chamber Life

Read manhwa A Noble Lady's Chamber Life / We had planned to celebrate our big success by treating ourselves to some Korean beef with my friend, but the novel turned out to be a dismal failure, and naturally, our plans for the beef went up in smoke.And then, something happened to me I possessed the supporting character, Adeline Macefrill, in that novel!Who is Adeline? She is the ultimate sidekick who wholeheartedly assists the protagonist, Rianna. She has a wide network, poking her nose into everything, gathering all sorts of news and information! I'm an extremely introverted person, so it's absurd that I ended up possessing such an outgoing character like Adeline!!To make matters worse, the novel's settings and reality differ. The supposedly well-behaved protagonist, Rianna, shows tremendous jealousy, and even the knight commander, Estian, who had a crush on Rianna, seems to take a liking to me?!Can't I just quietly enjoy my life in the corner, please?
