Marriage of convenience, ML are both generals that have came back from war recently, FL keeps trying to run away at first, bickering couple, hate to love, cold ML/warm FL, light hearted rom-com, only a tiny bit a angst that keeps the drama going.

It’s basically a remake except the night of the comet 2 has a happy ending and the plot is different. The only thing similar is the alternate universe concept!

there is cross dressing in both of them where the FL dresses as a male to sneak into a boy school! And then the FL ends up befriending the boys.

if I’m not wrong, both male leads travel into the past to change past events and to make sure they don’t have any regrets anymore.

both have narcissistic male leads and other similar traits. Also in both dramas the FL is searching for a boy from her childhood which turns out to be the ML.
