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
