Super short series. Looks dull and boring but if you can appreciate its beauty and what the show is trying to say, wow . 'When do we become adults?' though the show could be longer and have a more storylines, 4 episodes is enough to do so. It shows us how teenagers think nowadays and adolescents grow up, going through many thoughts, school, academic, family problems. As I'm also 17, I could probably relate to it as well so it stayed in my heart after watching it. Park Sieun (FL) was really prettyyy in this show omg (my bias) ... FL goes through stress and pressure to play well as a pianist from her divorced mother and her father who marries his mistress, and goes through sexual harrassment but she doesn't care so she becomes a call girl and accidentally meets the ML as he founds out about her secret. ML goes through heart break and disappointment to see his mother cheating on his father.. Two meet each other through fate and coincidence as he has a crush on the FL but both wants to end their lives. At the end, they talked to each other heart to heart when they were about to end their lives at Oi-do and feels bad for their parents so they head back.. and they held hands AHHHH beST PART at the end and fell asleep on the train back to Seoul with their heads lying on each other's shoulders implying they rely on each other now !! This drama needs you to read between the lines and appreciate the plotline to fully understand what's going on so it's prob why many gave this a low rating as they didn't rly understand and appreciate. But this deserves a higher rating for sure. The cinematography was amazing,it was dark but aesthetically pleasing as well. The OST fits well as well with the melo sad music, really like the song ^^ . Anyways 9/10, Sieun debuted with STAYC so idk if we can see her again acting in more shows but I hope so
