The game wants her at the ball any way possible. Every attempt she makes to get out of it only results in something weirder happening to make sure she gets there.
I think the game has figured out that she's not just an NPC anymore.
Her attempts to dodge attention has stuck her into a love triangle
->Swears that she's done involving herself in the game's storyPrince: Sana please come to the palace tomorrow we are having a ball
Sana: No thank you
Random messenger: Sana’s brother please come to the palace tomorrow
Sana’s brother: No thank you
Sana: Oh I’ll go instead
Sana:
Sana: Wait
Sana: I’ve made a terrible mistake
Wait, I didn't even made the connection when I read thatI'm not sure how you could have any doubt after pages 21 and 24.
I wonder how old the prince is? He seems much too old for Sana.
She wasn't a fake seller, she just over boasted her product which everyone does. Unless she lies to a noble, nothing will happen to her. Even more so since most of the people there are only there for the festivalSo no repercussions to the fake potion seller? Boooooooo. Also why in all that is holy would a commoner have a suitable nobility dress to see the king the next day? There is some awful stretches here to make it all work. Also whats the bet fake potion maker will switch out the potions to use her bad ones?
I'm dreading this stupid love triangle or reverse harem situation building up, I will give points to FMC actually trying to tell the Prince she can't see the future though.
