MC just wants to live a leisurely live as a concubine to the emperor and observes silently as an isekai girl goes into their world and falls in love with the emperor
much to her dismay, the emperor seems to grow feelings for her instead ((but she doesn't care, so))
isekai girl and scheming bitches try to overthrow MC's position as possible empress but because of their ignorance little do they know they are doing things in favor of MC instead
I don't want to be Empress!
