Helppp

Guys I read this one manga a while ago and I forgot to save it and now I can't find it anymore . I think it's a Korean one where the mc is this girl with black hair, bangs and she ties the hair into a ponytail. Basically she works for this chaebol family since she was little cuz her mom works for them too as a servant and the family has 3 kids, a pair of twins (one boy and one girl, MC has a crush on the boy twin) and a younger son. Apparently the younger son always had bad luck and also his name means cherry blossom in Korean and his mom got this lady with like superstitious powers or whatever to come and like see what's going on with him and she told the mom that he's got really bad luck and since the mc has good luck, they should get married so he can transfer his bad luck to her. So they get married and the girl kinda gets paid for getting married and she's also super into money like everytime somebody throws out high end brand stuff she takes it to resell and stuff and she saves up the money to travel the world like her dad did or smth like that. Pleaseeee help me find it
