Seungho sactificed his freedom to save Nakyum. He begged his father to save his beloved and in return he will be the son that his father wanted him to be. Lord Yoon agreed and Nakyum was set free and they framed Inhun for the crimes.
Seungho told a sick and unconscious Nakyum that even though they will have to part ways again, he did not abandon him. That no matter how much time passes, they will see each other again.
ByeonDuck did twist that knife huh..
My thoughts right now: Seungho will have to fix whatever is left of his reputation if he were to be the outstanding son that his father wants. Are we going down the path of the "arranged marriage trope?" Nakyum's heart will be shattered if Seungho ends up married to someone else. Will there be a time skip in the next chapters? We're in the final season of the manhwa, right? How many chapters are left? Are we gonna get side stories? Will this be a happy ending, a sad ending, or an open ending?
The moment when he realized his father was just manipulated and his great love for Seungho have caused him to ruin the very child he wanted to protect.
