I'm ngl the fl or even the entire plot is inconsistent??? And some events weren't even elaborated that well or even skipped, like the part where her sister fighting wasn't shown, just the fl being drenched in water while her sister was on the floor, or why the brawl in the bar started. Was it because of the fl? Was some random dude hitting on her or smth? Sometimes it don't even make sense ( ;∀;)
