I just checked out the spoilers abt nadia and it was not what i expected lmao
Basically mc asked her if she wanted to break her curse (by kissing her true love or smthg) and nadia said yes, so mc asked ml to kiss nadia to break her curse and ml refuse. He even confessed that he loves mc.
Mc then tells nadia it wont be possible for her to break her curse but nadia then just kisses mc instead lol. Apparently the person nadia was in love with was mc and not the ml but people thought she was in love with ml the whole time
According to the spoilers in the korean translation, the word nadia uses to when giving her flowers translate to "your highness/majesty" and doesnt clarify which majesty (king or queen)
And because of that the servants had completely assumed nadia meant the ml when giving her flowers, when she actually meant to give to mc
The fact that this is their first official date together and its already going terribly
