I understand but I don’t???!!

I am stupid so naturally I ran to the comments. So system fcks up the grand duke by hearing the opposite of what mc says cuz grand duke’s wish is probably mc loving him back. Mc already loves him sooo thats why they are always rank one? What happens again if they grant their grand duke’s wish? I feel like the execution of this manhwa can be better. Or maybe its just the translation cuz I am confused af most of the time. Also that reveal just made me feel even stupid. Even after knowing what it means it’s still all over the place in my brain bruh what.. If a lot of people doesnt get your story telling (I know cuz we alot in this comment section) then the story telling is stupid or its just that the artist is green. Is this an adaptation? If there is a source material like a light novel and still the presentation is confusing..well, i dont know what to say
