Neither do I but I am happy that he fell in love with a good person, and that he can admit his feelings and let them go, instead of pursuing her aggressively. I quite like the prince. He can separate his feelings from his decisions even if he doesn’t want to. I hope he finds someone else he loves and gets to marry them, even if it isn’t necessarily a romantic love.
I quite like the prince also, because he loves her he acknowledges that she would never be happy by his side. Trapped in politics and within castle walls, so I really do hope he finds new love and somebody better suited for the seat next to him. Kasia is a knight so even if she has been learning emotions and about people in this life she could never be anything else but a knight, so him loving her enough to let her go is so praiseworthy in my book.
IM SORRY BUT I DONT SHIP KASIA WITH THE PRINCE
