Honestly, I wished uke said something to the bitch like, "I'll marry you as long as I can still fuck your brother and I'll only fuck you if you're ovulating and you'll leave the child to me and your brother to raise." And then after they actually got married I wished he was intimate with him in front of her from day one.

Anyone willing to tell me why there was a fake in the first place when they kicked her out?

Form what I understood MC is the og got kicked out then saved by the holy, regretting what they did the family started looking for og, then the holy who saved MC asked her to play the fake knowing she is the og, then MC tell the truth to the family, then leave, the fake arrive in the time MC was not here in order to get the title of the noble family, i guess and the they asked MC to come back to be the maid.
But what i don't understand why don't they asked any of them to use earth magic to see who is the real one because this was the exact thing that make them kick og out, because fake definitely not know how to use earth magic, i think

I think there are two reasons.
One is so that some of the family can relieve their guilt for locking her away in a castle for so long as a child and abandoning her there. Two is because the other half of the family knew she was a fake anyway and allowed her to stay as a pawn for their plans. This part also means they skipped the Earth magic test or did it anyway and lied about the results the whole time.

For someone who didn't want the hassle of maintaining long hair he sure is implementing hair care for baby girl early.
