Oops, I’m Not a Murphy!

Yulia is feeding the fish when she slips and goes into the pond, and coming out of it she understands something she had not before. Her parents are not her parents. The five brothers who have looked after her all her life are not her brothers. She is the Savery family's fake daughter, and the real one is coming back. Anyone in her position would start scheming to hold on to the house and the money. Yulia works out that she is going to lose all of it whatever she does, so she stops trying and simply lies there. On the day the real heiress walks in the door, the five brothers put themselves between the two women and ask if the girl can be allowed to stay on anyway, since her head does not work quite right and it would not be safe to have her out on her own.
