This show was absoutly stunning. I haven't had the motivation to watch any new shows. My friend recommended it to me and I finished it in 2 or 3 days (since I am a student). I used to love kdramas, animes, watching tv in general but I haven't had motivation to do most things anymore. Just letting myself rewatch the same things again as if I could just repeat time. This show definetly has given me the joy I got from enjoying other shows. The suspenful buildup, the detail, ect... Definetly a must watch.
I built a connection to the characters because lots of them were just like normal people in the real world. Going through their hard times and seeking some esacpe, or assurance that everything will work out in the end.
