When I was really bored in the past, I once had a heated debate with my best friend on this question- What would you do if you transmigrate to an entire different world?
My friend said she would be doomed. Which I agree with, a lot. I am not particularly smart. I do not have any special talents. I for one am quite certain that I won't be able to become the first female general that fight back conquering enemies or the queen that unites the continent or something of that kind. I should be glad if I was not killed immediately.
And another thing that's never mentioned in those novels is that you will miss your family. Extremely. Desperately. It is like your heart gets carved out. And you feel empty inside. This is not like studying overseas where you can message your mother with a click of finger. You're now living in a totally different world. A different universe. A fictional world. The hard cold truth really shatters one's heart.
