This drama was one of the very best inhad seen in 2021 , the writer did a very fine job of mixing a simple plot in a outstanding trajectory and hats off to the cast who performed their roles so well .( SPOILER AHEAD ) ep16 was a total hit when we see han bi soo showing that he lived for the next 49 years but then we jump back to reality and he disappeared that was by far the most touching and tearjerking moment ........ lastly i would say this is one of the best kdrama for any romance lover out there.
