Forgotten Title QT-switched at birth and reborn character

1. I only remember a specific arc. In this arc the mc is transmigrated as a baby who is abused by his 'mother'(turns out that she switched her baby with the mc). The mc had to make the father find out the truth. Her real daughter is reborn and knows that she is the real daughter, so she tries to learn anything that will help her become accepted in the upper society

 

I think this is an arc in The Villain is too cute

Edit: Chs 38-83

 

Yes it was. Thank u . I hate not remembering things
