May be some people didn't like the show that much but its their own opinion. This drama is just 7 episodes long, and, of course they rushed the ending, however I think the cast was great. And I'm expecting a better and long story if there will be a season 2.
I think FL was indecisive but there was a reason for it. She lived her life alone without any parental guidance, so when a lone child faces problem, then it becomes hard to find right from wrong, and she was high schooler, and then a burden of pregnancy was just wild.
And I don't understand why the writers are obsessed with sending the FL to New york, you will know after watching.
Ri-an was a main character but he has not gotten a single real scene, like when ML solve some mystery or act like a hero. Writers did him wrong.
I think the story is all about Kang Ha and him solving the mystery of his brother's death, it would be better if the writers just made him the sole main character.?
Overall the cast was good, they could make a better story.
If you watch it, it would caome to and ened before you know, so I recommend you to watch this, the views are just great.
