Goodbye in July (2021)

The plot where the heroine does not get into her desired class is similar. In both the dramas the heroines make use of their classmates to their benefit. Gradually they realise that there is friendship and love which is also important in life.

both female leads failed to enroll into their favorite class/college due to an accident, and both of them first approached their classe mates to use them and ended up becoming part of their respective classes and they even changed them into hard working successful students.
