truee, my bet is that she's dating Yoo-bin ou they are besties but they are keeping secret due to... well, none of the parents would be happy pan_eating_noodles
or yoo-bin might be in love with so-yi but so-yi dismisses her thinking she's young and immature or something and it's a whole debacle
She looks cocky just like her mom lol, all the characters kinda got their mom personality kk
