Then it would just be another cliché of fl getting living the happy ever after, which has been too overused. I personallylove that they stuck with their original concept and plot and built around it and not erase the whole point of the story just to push the happy ending agenda. It felt more realistic this way.
A lot of manhwa adaptions are already changing their endings for the worse so I don't really care, I just want the FL to be happy. She deserves that with all her suffering throughout her short life. Shoot me but I don't read for realism in fantasy genre. I like cliche happy endings after a long journey of tragedies.
A lot of manhwas changed their adaptations so I don't see why not they wouldn't change this so Karina will live a happy long life, no?
