Never thought that school bullying can cause lifetime scars. This was actually a great piece. Though the presentation or I should say the structure of the play wasn't appealing but the story was great. The parallel narrative that's moving with 3 line space, first line (from where the story started) is present when Han Xiao Ting disappears parallel with the second line which is 2018, a year before she went missing parallel with the third line that is their high school life in year 2008, was really hasty but this hastiness helped the story to keep the curiosity of the intense relationship between the 4 ladies.
The story had many social issues and unknowingly while watching you'd be trapped in the questions, the questions that'll make you realize how small things matter, how one's perspective of accepting the reality or running away matters, how parents' attitude towards their children matter. This story actually acted as a mock test, a test for audience to review their ignorance towards the small issues of one's teenage.
I'd say there are only 16 episodes if you have time or I should say if you have nothing to watch then do give this drama a chance.
If we talk about acting then I'm speechless.

[so 1 star was taken away because of the hasty presentation and 0.5 star was taken away because of dancing screen when the intense moments of the story were going on.]
