Forgotten Y/N x Shalnark

Y/n was all alone. Abadon by those she thought were friends. Y/n was only 12 when her sister Shizuku and the spiders left Meteor City Leaving her there alone. And only 15 when she was raped and had her baby girl.
After getting on her feet two years after giving birth, she left for York New and was taken in off the street by a kind old man. Y/n's now a self-made millionaire and supports herself and her daughter by her own income.

What will happen when she reunites with sister and the spiders 5 years after they abandon her, and a certain someone tries to break down her newly built walls?
