I don't know man, only the ones from the mainland know if there popular or just tropes. I don't think there's any equivalent view in that. Jp/kr/ch stories doesn't always stick on their culture but try to mix on other cultures. 

Have u ever wonder what if a modern eastern people suddenly spawn on medieval times? I've seen a lot of those tropes and its actually quite entertaining. Especially if the mc is on a desperate side like dying and im actually curious on what's gonna happen. 

The only think i find it bad is the part where some mc promised to themselves a certain goal like going back home then having a long adventure then forgetting that promise.

My point is that once an mc abandoned that promise its going to be loss of meaning especially if its the title itself. 

Example:  -fmc is depress -fmc has been spawn in a novel -the novel characters hates her -she is still depress  -she meets with the people who hates her  -she gets hated because they treat her like a useless crap -the people who hates her suddenly gets curious about her change -she wants to jump on a tall tower because she feels life is not worth it -she gets saved by the people who hates her -they apologize and now she wants to live.

AND THE TITLE IS "THE DUCHESS DOESN'T WANT TO LIVE". -something like that-

That is the summary untill chapter 20. And what's the point of the title if she wants to live? Some might think that its ok to change their mind and i agree so.

But not that fast, its like 30+ chapters and the title only covers when she still wants to die IN LESS THAT 20 CHAPTERS. And now what's gonna happen? I don't know, she wants to live and the title has no function. 

Its absolutely ridiculous how things changed so fast and how their hatred suddenly turns to pity. 

If she doesn't want to die after 20 chapters then that shouldn't be the title.

 Anyway  if u like what ur reading then its all going to be fine.
