Jusui is cute... but because of how I have been reading Apothecary's Diaries for some years now, I know that the women that are given to such harem, especially the ones that were practically bred for the purpose and especially the young ones, were seen as nothing more than breeding mares.
Sure, doubt she has had any difficulties in life, but not an enviable position actually, and as the youngest with the youngest son... her position is beyond fragile... not because she isn't in a favorable position, she is of very good "breeding", but because if she is the one chosen, girl will be nothing more than a puppet... if she doesn't catch a case of an early grave.
