I really Liked the Poster and the Title, that's the main reason for me to watch. Like any drama I didn't have expectation much. It gets u drawn slowly, the short episodes gives u motivation to finish it. It's full of mystery and thrill events.
The Characters are amazing, the Monologs by each of them is catchy. Every word they say holds wisdom of life not only for 19 year old. The poems and analysis by the the main lead is inspiring.
I really loved the OST, it's unique. Especially the SOS OST, it is short and has a huge impact, u get sucked and teary whenever it get started.
I really recommend u to watch it
