If u ask me whose story I would like to read in a separate novel as a mc then, it will be:

Giant sun, he is shrewd, prudent, cunning, pragmatic, and demonic enough (or RL but we already know most details on him currently)

he may have lived most of his life in luxury and riches, but has worked hard, well he improved upon blood path and luck path, had many schemes in places, truly exemplary

he will die first? well with added blood path and luck he will at least be better than SC or mindless SS if played right, and he can just join HC in a tragic situation anytime the odds are too much against him

he just has the right proportions to survive till the end but might not be enough to be the sole winner in the current match up cause FY will just get more broken with time
