In another life and a diff yaoi series, I wouldve LOVED to see his majesty and the MC get together (but preferably not incest), where the king's yandere-Ness is loved and accepted by the MC and their love is reciprocal. Alas, we are in green flag non-yandere, puppy seme territory. Still good tho! Im happy theyre happy ヾ(❀╹◡╹)ノ~
