I don't remember much but there is this time skip and the ml escapes and goes back to his kingdom this part was a bit angsty since i don't think he said goodbye? And then when they grow up a bit more the generals son tries to marry the fl and there was a little drama if im not wrong and then there is a news that the new ruler of the other kingdom killed his way up to the throne and he sent a proposal to our fl to which there was opposition since everyone loves her.
There was something with the crown prince too if I remember right but i forgot what exactly it was..
I hope my answer was satisfactory enough

I remember reading the novel and oh boy it gets quite angsty later on
I don't remember fully but yes I remember the pain
