Amazing story, great cast. This is based on an introverted high school girl who is secretly a social media star. Things get messy as her secret is slowly discovered by her classmates. It is mostly dark type of drama with less or negligible romance, comedy or fun. It's really captivating story with tickling cliffhangers at end of each episode, that make you crave to watch next. I completed whole drama in a day. The thing is you may find the dual side of the character annoying, but again the 4 main lead have a tragic backstory. It's an underrated drama, according to me....
