For me it doesn't matter since Sae also help Kai in his difficult days. He had Sae when he has nothing and still the same when he has everything. And their relationship is not toxic, they help each other to realize their own worth and boost confidence.
I'm not gonna lie but the romance betweem sae and kai discouraged me big time-
I was able to ignore it and go through this because this manga is an absolute masterpiece
