Help me find this manwha (did I spell that right?) plz

I read this manwha a few years ago, but I can't for the life of me remember the name（/TДT)/

Its about this pair of twin who upon their birth, a fortune teller came and said that one of the twin would cause the death of I think the grandfather and so he forced the mother to kill the bad luck twin. Oh and the twins are girls. But the mother couldn't bring herself to kill her child and switched the bad luck twin with the good luck twin as the mother wanted to prove the prophecy wrong and left her somewhere (I think). So the grandfather raised the bad luck twin and the good luck twin was raised somewhere else.

Years later the twins meet again, but the bad luck twin was spoiled as their family was rich and the good luck twin's adopted family was poor. So the bad luck twin treated the good luck twin badly and Im pretty sure the bad luck twin made the good luck twin trade places with her for a party event or something. Stuff happened and so the good luck twin was accepted into the rich family and the bad luck twin was kicked out. That's all I remember. Sorry if I couldn't be more specific (￣∇￣")
