After Dressing up as a Top Student, I Counterattacked

[Strong women, strong men, sweet pets, bosses, geniuses, hackers, top academics, music...] What is it like to wake up and find that you have traveled to a parallel world? Before time travel, she was a beautiful school beauty who was famous for her poor grades. She was beautiful, had sweet songs, and had a dark smile. My father doesn't love my mother, and I have no money, no house, no savings. After traveling through time, she discovered that except for her face, everything about herself in this world was completely opposite to the original world. Her father dotes on her mother, she spends endless money, and she gets perfect marks on the test papers. In order not to be discovered by others that she is a subcontractor, she can only break through herself and challenge her limits. Slowly, she discovers that she seems to have many unknown identities in this world. While she accepts her identity, there seems to be an invisible hand controlling it all. After the fog clears, what kind of secrets are hidden?
