Diary of a Concubine's Daughter

A blind woman transmigrates into the home of a wealthy family with both parents alive and all her siblings around. She can count herself lucky! A concubine-born daughter? But one whose father doesn't care for her and whose birth mother is weak? And a concubine-born daughter who has to choose sides with the legitimate faction? In a grand household like this, picking the wrong side means you'll be in for a rough time. Should she keep her head down and become a concubine-born daughter who follows everyone around, or hold her head high and become a scheming woman who takes a different path?
