Well , i make this account a few minutes ago so this will be my first review. Thz for reading .. Xo xo ^^ I like school drams so really interest in this one before i start to watch it . Also it becoz of kim so hyum cuz i'm her fan boy . Okay, let's start with storyline , it was pretty intresting that the story also starts with a twist of eum byul disapperance . Some middle parts are a little bit boring but it still really worth to watch . The acting is good . KSH is really good here too as i expected . I love how she plays two characters with such talent . Acturally , i love eum bi face reactions and character than eun byul . KHS was really a bae ^^ . Well , i also love the bully girl kang so yeong play by jo soo hyang . Never see her before but her acting is pretty good . Everytime she on screen , i was like “ wow .. there goes my evil girl ". Abt the two male leads , well i'm a fan boy so i don't know much like how to write a good rewiew on them like fan girls .. Srry xD . But i can say that the second one is pretty good at acting . Later , i know that he was from BtoB and wow , kpop guys can act too . Too bad eum bi didn't end up with him . Music is really good too . I like reset , return , i'll listen to what you have to say and love song . Sure , i will rewatch this again for KSH and some romance ^^
