Mind you I am pulling this from memory but the original story was something along the lines of MC dad died, lawyer screwed them over and took everything so they were broke and lost the house, his mother and sister(s) moved in with his aunt but due to her previously finding out that he and his cousin Robin were messing around she wouldn't let him move in with his family and he had to go it alone. Mom thought he was staying with friends but he didnt cause it would be humiliating so he had to sneak into the aunts house and avoid her, blah blah blah.Uh, that wouldn't make any sense. From the beginning Julia and Katherine were foster mothers to MC. Julia was also Stepmother...
PS story was changed a bit, but there sneaking is also there.
This seems to be a completely revamped story from what I remember the original one being to eliminate the incest content.
