Winzy's manga / #Wtf is this(1)

I've never read such trashy plot and characters etc. Wtf? Is she dumb? Cause that's the way I see it. She's always clueless and acting like a teenager uhmmm aren't you supposed to be 22 yrsold? You act so immature to be a noble young lady. Fck i regret reading this. I left at ch29 cause every chapter sucks. Talk abt duplicated chaps every single time
