Touch My Sister? You're doomed!

Two babies were switched at the hospital where they were born. One of them, Lin Yuxin, grew up as the daughter of the Shen family and spent twenty years in that house. Shen Kerou, the girl who had been born to the Shens, came back at twenty and the switch came out. The parents turned on Lin Yuxin at once, and the treatment she got in the house went downhill from there. She left to find the family she had come from, the Lins, and they had been searching for her the whole time. She has five brothers there, all with money and standing behind them. Shen Kerou, before she took her place with the Shens, found out that Ji Chuxu had been saved by the real Shen daughter years earlier and had never learned who it was. She set about being taken for that person so the marriage would come to her.
