Oh! My Empress OME

Kim Su Won, a corporate slave in the modern world with average skills in life, is abandoned by her boyfriend of two years. In her sorrow, she gets alcohol poisoning and transmigrates to a historical transmigration web novel. Very cliché, right? However, she gets transmigrated not into a side character who ends up taking place of the main character nor the villainess who flips the whole plot. Neither does she end up in the body of a male character to make the novel a gender bender. She has ended up in the body of the 12 years old female lead, Emmeline Whittemore, the daughter of one of the richest ducal families in the kingdom of Krislabet, four years before the original transmigration was to happen in the novel.
“Past memories of the original body? Check.”
“I must have finally gotten some magical powers.”
“No? It’s okay, may be some spiritual space?”
“That is absent too! How about some magical item?”
“That’s not present either? Must be some hidden cultivation techniques?”
“No? No magical pets either? Then it must be a system for sure! I must complete quests and level up!”
“No? F***! I am doomed!”
Now Kim Su Won has to navigate this completely new world, without much knowledge apart from the characters that will appear four years later in Emmeline Whittemore’s life. Follow Kim Su Won as she adjusts to the new life, correcting the past regrets she had in her original life and learning the rules and regulations of this place where the schemes abound, and each white lotus is racing towards becoming the crown princess.
Wait a minute! And what about the girl who was supposed to transmigrate originally into Emmeline Whittemore’s body? What will be the fate of Kim Su Won?
