Quick transmigration + multiple TV universes + strong female lead + satisfying story + romance depending on the situation
Usually, two worlds are combined, though there may be more.
The female lead, Lin Xian, is no conventional good person. It mainly depends on how her role is set up.
The plot may be exaggerated, so please be gentle in your reviews. I can't guarantee it will be good, and I'm still slowly figuring things out.
The first few worlds are all Korean dramas.
World One: The Crown of Ambition (Anna + The K2)
World Two: Persuading People to Study Medicine (Sky Castle + The World of My 17 + Hospital Playlist)
World Three: The School Ecosystem (The Heirs + Weak Hero Class 1 + The Glory + Melancholia)
World Four: Raising Wild Boars in Captivity (Kingdom: Ashin of the North + The Man Who Lives with the King)
World Five: True Feelings and Schemes (The Handmaiden + Love and Romance + Lust, Caution)
