I just readed the chapter before new today and this is really interesting! At first i didn't expect that Redhead just gonna come in and they didn't close doors, but well it happened. Good thing MC isn't a coward and confronted her, somehow protecting Nayeon. She also told her that "This time, that's not true" so Nayeon probably thinking about MC in more serious way(which is awesome). I wonder what kind of game they will play and i hope MC will win this, surprising and dominating Redhead or some drama will happen. Stepmother is really mysterious right now because we don't know anything about her, she just acting kind, but i think she hiding something important and her true self. I'm waiting for next chapter so much.
